I encountered this peculiarity (and more) after replacing the old throttle body with a less-old, freshly-cleaned throttle body on my 98 with a 99 motor. I just finished following your instructions; idles right and runs like the masterpiece of German automotive engineering that it is. Many thanks!
Thank you! I bought this 98 Jetta last spring, along with a nearly identical parts car, as a temporary car during hard times. It became something of a project for me until a person I loaned it to nearly totaled it in a front-end collision. I've been struggling with oddities since last August and it has been difficult to find good Volkswagen info online. This one short video has provided me with more help than nearly anything I have found in the last nine months. Keep up the good work.
I was wondering if soon you could do a video like cleaning a IAC for the MK3 ABA 2.0. I have not clean mine yet but is really good to see your videos for me to avoid breaking anything or problems hehe.. thanks for the help always man. I'm learning everyday and i keep watching all of your videos one by one. Peace :)
Hi, thank you for watching! I use "brake parts cleaner" to clean the IAC / Idle Stabilizer. I remove the valve and then I spray it with brake cleaner (you can also use MAF cleaner). After it is full with the cleaner, I use a fuel injector tester to "trigger" the valve, so that it opens & closes rapidly. I do this a few times and then install the IAC valve again. I will try to remember to make a video about this... but not sure how soon I will get the chance.
tanner rubottom The rpm code too low at idle is the result of whatever is causing the idle to be too low (rich mixture, lazy O2, bad MAF, etc). Solve the rich running issue and you will probably solve the rpm code at the same time.
I was wondering on my 95 Jetta 2.0 aba, two things.... I have a rather low idle, anywhere from 500 to just under 750,i also for other easons replaced my air filter,and cleaned the maf and the throtlle body, I am wonderring what to do next? And also I get A LOT of oil in my intake and, air filter, is this due to a faulty pcv?
stupidrelaoded If you have an idle stabilizer to the right of the intake manifold, cleaning the throttle body will not change anything... since the stabilizer is used to adjust idle, not the throttle body. The intake boot has been redesigned a few years after 95. You can install the updated version that has a PCV heater & vacuum hose, that reduce / limit the amount of oil in the intake. Go to a wrecking yard and remove the intake boot from a 98 model 2.0 and install on your car.
stupidrelaoded Here are a couple of screen captures of the intake boots. Old style (yours looks like this one): fkh161.ca/VW/ABAold.jpg New style (with added PCV heater and vacuum hose to suck out oil): fkh161.ca/VW/ABAnew.jpg The red line is the vacuum hose that runs to the throttle body and the blue line is the PCV heater.
Hi Thomas, i have an 2002 VW Cabrio, took it to a shop and they say the throttle is out/failing and needs to be replaced. I ordered it and going to replace it by my self. Is there something else that i have to do other than replace the old for the new one? Should it align by itself or i need to use VAGCOM tool?? Thanks a lot
Peace and greetings , I have a 2012 vw Jetta se 2.5 and just changed the throttle body , map sensor , spark plugs and coils , and when I put the key to the on position before starting the engine the EPC , check engine , and battery light shows up on the dashboard, and when I turn on the engine it all clears but shakes and has rough idle. I try to clear codes using OBDeleven but it keeps popping up new codes after every time I start the car
thanks a lot its 2004 3rz-fe engine 2.7litre the idle not drop all hoses in great condition no leaks ..............thanks i need to take the vehicle for a long cruise thin every thing will be cleared .
hello there and thanks for the useful video, I was wondering if you knew what was the idle rpm for an 94 jetta 2.0? it's reving like the vw of your video just above 800 rpm
Maybe you can help me solve an issue with my mk3 (aba motor) ... bought it for dirt cheap just to flip. And it ran good on my hour drive home but a little cold. Replaced the thermostat and it solved the problem. But the car doesn't want to idle. It won't idle. I will keep dying, also hesitates and jerks when driving. I cleaned out the intake and throttle body (entire intake soaked in oil, including maf) cleaned out the maf and it fixed the issue for about 10 minutes and now it keeps doing the same thing. Any suggestions? Thanks much appreciated.
Motorized throttle body or idle stabilizer next to the intake? Not sure... could be fuel related. There's a TSB that addresses the oil in the intake... install the later style intake tube that has the PCV heater & vacuum hose. If it runs better after cleaning MAF, start with the oil issue.
No. The high idle was due to the fact that the ECM was holding the throttle open in the old "learned" position. As the throttle bore gets dirty, the ECM opens the bore more and more to maintain a correct idle. Once the dirt is wiped away, lots of air can get past the throttle... usually the ECM will "relearn" the new idle setting (will lower the idle speed over time as it learns it). A quicker way to "teach" the ECM a new idle speed / stop, is to disconnect the battery, touch the cable clamps together... this wipes the memory of the "old learned throttle position". I usually use a scan tool, but I made this video to show that it can be done without a scan tool.
Hello there I have a lotus exige s with the toyota 2ZZ engine in it and after the mechanic took my TB out for cleaning I have high idle problem @ 1500rpm and takes awhile to drop back down to normal 800rpm..... Help!!!! What u think I can do?????
It might take a bit of time to relearn on its own... I'm not sure if there is a specific procedure that needs to be followed after cleaning (Throttle Adaptation) like on VW & Audi engines. Have you already tried to disconnect the battery and doing a capacitive discharge like in this video? I can not guarantee that it will work, or that something goes wrong. The fact that it eventually does come down to 800, tells me that the ECM has control of "whatever device is used to adjust idle" (throttle plate or Idle valve / solenoid).
This is a great video. i actually took throttle body off my tahoe and cleaned it. didnt move the throttle door much. but now i have 900 at stop light and sometimes when i put it in park it jumps up to 1500-2000 and wont go down. think this will do the trick?
If you cleaned dirt from the throttle bore, you will now have more air flow, which can account for the higher idle. I'm not familiar with the Tahoe Idle Control, but if the throttle is used, then yes, it could help. The capacitive discharge clears "learned / stored" Idle / Throttle positions, the ECM then reverts back to Factory Values. It should relearn on its own, but might take a while.
***** thanks man yeah i think i moved the door too much while cleaning and the sensors inside got out of whack. check this out. sounds like alot or do all even need to be done www.scribd.com/fullscreen/40028805?access_key=key-1oip081ma7zg9vv5nzjl&allow_share=true&view_mode=scroll
Hi, i have a 2003 seat Leon 1.6 16v and the revs are playing below 700rpm and its stinks of petrol when you start it but before it used to run with the same problem. Now it starts, idles under 1000 doesn't rev, cuts out when it wants. It's had three throttle bodies on it and all three didn't change the problem. Any ideas ? Could it be the ECU ?
I changed throttle body but car does not start. It turns over but it’s not catching. Any thoughts on would it could be? It didn’t have a gasket on the old one so I don’t have one on the new one... do you think that could be the problem
Year, make, modle, engine (in case it is not a mk3/A3 VW Jetta / Golf)? Was it running with the old one? If yes, install the old one to see if it starts again. There's usually a paper like gasket... lack of gasket should not be an issue. Have you checked for spark & fuel? Turn the engine to TDC #1 and show me the TDC marks on the cam gear and on the flywheel / torque converter at the transmission... also the location of the distributor rotor. You can record & upload a video to your channel and then post the link here, so that I can go check it out. Or, you can click on the fkh161 link in the description and then click "tool request" to send me the images. The more I know (why did you replace the throttle body / what was the original issue etc) the better I can help.
I just cleaned my throttle body and cranked it up and it idle up to 2500 rpm and slowly started going up more so I cut it off do you what that could be it a 2012 Chevy Malibu
If it's an electronically controlled throttle body, then the ecm needs to relearn "idle". It is still using the old / dirty idle throttle position... which is now clean and allows more air past the throttle (hence, high idle). The quick way for the ecm to relearn the new idle position, is to use a scan tool that can activate the relearn setting. The ecm should be able to relearn without a scan tool... just like it learned to adjust / compensate over time for the dirty throttle body. Driving for a day or so "should" give it a chance to relearn.
I drive a 96 Mk3 (A3) GTI 2.0. After killing the battery one day, the throttle began acting very strange. When depressing the accelerator, there is little or no response for a moment. If I hold it at the same position, after about a second the revs will jump to where they should be. The same happens if I manually press the throttle. Idle is just fine. -- Do you think a capacitive discharge would solve this?
A discharge can't hurt, so give it a try. Be sure to clean the throttle bore first or you might end up with a low idle or stalling at idle. If your throttle body is not motorized (only a cable is attached) the issue is not with the throttle. I have a feeling that this symptom is not a throttle issue... see how the discharge goes and let me know. You will have to enter your radio code if still a stock unit.
***** Awesome, I appreciate it! I will let you know how it goes after I try. -- Also, I replaced the PCV and its grommet today, (was cracked and not sealing well) and it seemed to help.
+Thomas EXOVCDS hello, i have high idle 1100rpm after cleaning throotle. Throotle was adapting and have the same high idle. Only when i have first start and when car is cold idle is ok and after temperature is 90c idle go on 1100rpm. I use another throotle but the same problem. What you sugest? thanks
edin zuko What car / engine? Disconnect the battery cables and touch the cables together for a few seconds. Reconnect to the battery and see if things are different.
Hey i have a 2007 dodge nitro rt i got the pcv replaced and they cleaned the throttle body at the shop..after that it was in very high idle higher than when i brought it in for them to fix it...the bolt (z) now stays on my dash while driving now never did that before and when at a light or in park the symbol comes on this is draining can you help me out
It could be (just like with these older VW's)... that after cleaning the throttle body, the ECM has a hard time relearning Idle Speed Settings. It should be able to do so "over time"... in some case, a scan tool is needed to "force" the relearn process.
hi, it doesn't work with me the rpm should be around 650-750 but its around 800-900 after i take the throttle body off i cleaned it without disassembled it i think it should be disassembled the idle air control assembly and clean the valve inside it i think the valve of the isc is stoke - i was replaced the spark plugs with a new ngk bkr5es-11 that recommended for toyota hiace in UK ngk branch i notice after finish the job some drops of water came of the exhaust that's mean perfect burning.
Capacitive discharge takes a few seconds... for those who take coffee or smoke breaks, 10min will work fine. New cars with more modules, might require more time... haven't had one of those yet.
Hi i have a problem with vw golf mk3 with AEE engine and after new throttle body and after alignment with vcds car idles at 4000rpm for a 30 sec and this happens only at cold start when its at high temp runs normaly at 750rpms can you help me please
Do u guys ever notice a high idle after replacing a battery or clearing codes on a vehicle with a highflow aftermarket filter? My theory on why that happens is the the car won't start making idle adjustments until hundreds of miles so it goes to a default idle not designed for a high flow filter and that's how u get high idle. Does that theory make sense?
As the throttle body bore gets dirty/ restricts air flow (at idle) the ECU has to open the throttle more to get the correct idle. Once the throttle bore is clean, because the ECU is still using the learned position (of a dirty throttle bore), the idle is higher than it should be, due to the higher air flow. Over time, the ecu should relearn / lower the high idle. The quickest way is with a scan tool or capacitive discharge. Newer vehicles with faster ecu processors can relearn idle speed much quicker.
Hey will a mk3 2.0 run like crap rough idle when I give it gas it sputters no power. Just did the timing belt. Oh btw I broke the pcv valve would that cause it ?
If it ran fine before the timing belt job, it should run the same after... if not, double check what you did. Depending on how / where the break is... it can affect air flow through the MAF... which can / will affect engine performance. You can block off the PCV where it enters the intake tube (ahead of the throttle) to see if it runs better (remove the pcv hose from the intake tube and block the hole in the intake tube somehow for testing).
hello. I have a 98 jetta 2.0. the idle will randomly sputter sometimes. go down to 500 rpms or so. sometimes it Wil die if I dont give it gas and other times it will go back to normal. it accelerates fine drives fine. and does it hot or cold. There's two engine. code one says its running to rich and the other is rpms to low at idle. any ideas? its had a tune up recently, I have new belts just need time, and there used to be an issue with the coolant temp sensor.
You have probably solved your problem a long time ago, but the solution is to clean your throttle body. That's how easy it is to fix :D I have tried it on two cars with the same problem as yours and it worked both times :)
I cleaned my throttle body last weekend. It was nasty. After that I got high iddle. Next day I got check engine light. Needed to replace o2 sensors bank 1 and 2. Mechanic told me to clear the codes first because it’s maybe just a fail safe mode. Something like that. I cleared them and The checking engine light hasn’t come back however I still have the high iddle. I tried to reset the throttle body but nothing. Should i try this method?
If you don't have a scan tool that can activate "throttle adaptation / alignment", then yes... this is a quick & cheap way to do it. If the idle is still high after, then something else might be going on. Year, make, model, engine?
hey i just purchased a 2002 vw beetle. After about an hour on the highway, the car stalled and i cranked the car a few times and it started. I drove another 20 mins and it happened again. It does it randomly now and then. What are the isses, i don't think it's gas or fuel pump. I runs great and is arching out from a bad plug wire but is fine. I have to fix that wire too. I've read about the crank position sensor, Idle speed control or maybe my distributor is worm from the arching. I'll clean my MAF but don't think that's it.you've done these cars 100 times over, what do you think. it runs great ,on the highway going 60mph and it just stalls.
+mike shiva Hi... sorry, forgot to reply yesterday! Yes, could be crankshaft position sensor (engine speed sensor). If you have a scan tool and you get a G28 speed sensor code, odds are that the sensor is old & starting to act-up. They are easy to change... here's an old video of mine: ruclips.net/video/LldC6CuXYoQ/видео.html the sensor is located to the right of the oil filter, mounted at the base of the block, close to the transmission.
your the man dude. your videos have helped me many times and you actually reply.if there is a rating or survey,send the like too. The car is dangerous on the road.
Hello, i have a vw golf mk 3 1.8 GL, i clean the throotle body, and the car going to high idle, the revolutions move high and down, but the car don´t off. I make the procedure, but don´t work, maybe driving the car for a while, the pcm learn the new condition. The only thing that i don´t know how do it is reset the clock and radio, how i do it? Thanks.
Touching the battery cables together "should" reset the computer... if you still have a high idle, the computer "should" relearn and lower the idle by itself. The buttons in the instrument cluster are used to reset the clock. For the radio, you need to enter a 4 digit pin number when the radio says "Safe". Press am/fm & Scan at the same time until you see 1000, then enter the pin number using the station numbers. If you do not have a pin number for the radio, you will need to contact a VW dealer so that they can give you the pin. They will require the VIN number from the vehicle as well as the Serial number of the radio.
Hey I have a 2011 Silverado 1500 5.3 I cleaned the throttle body because my engine light came on and said “Engine powering down” and I wouldn’t go over 20mph. After I cleaned it I started my truck and rpms shot up to 30000 and wouldn’t drop. I’m burning gas a lot more then usual I don’t know what to do next.
I don't have any experience with Silverado's... try a Domestic Automotive RUclips channel. If nobody replies to your posts, let me know and I'll do some research for you.
No... this engine / year of 2.0L ABA does not have an IAC. The ECM adjusts the position of the throttle plate to increase or decrease the engine rpm / idle. 2.0L ABA engine from 1994 to 1997 used an IAC valve... located to the right of the intake manifold above the valve cover.
@@ChaseHollandProductions Key on engine off... what are throttle plate values when viewed with a scan tool? Throttle angle, gas pedal position... does it pass throttle body alignment / adaptation? Is the carpet clear of the gas pedal?
I ve got problem with golf 3 1.8monopoint 90 hp on petrol on cold start it revs about 2000 rpm and it drop at 1300 and you need to drive to long to come on 900 can the reset help or it has onother problem
@@EXOVCDS thanks contemplating on whether I need to bring this up to the repair shop that just returned my car after throttle body and MAF cleaning or if I should wait it out….
@@Arlyndonnelly you can do a quick visual inspection to see if the throttle cable is not adjusted too tight... possibly keeping the throttle open slightly.
Hi I have vw golf 4 and i did computer check today and it gave code # 533 idle control speed so my quistion is should i replace it or clean it again because it happend when i cleaned throttle body and car became very raugh and have 1200rpm. Thanks
I'm not sure if this applies to your car or if that is the code you had. Seems to be, but usually scanners will provide "P" codes... p0171 for instance.
+Sasuke Uchiha You have a high idle with a new throttle body? Yes, a capacitive discharge can help when a throttle adaptation / alignment does not help or if a scan tool is not available.
+Sasuke Uchiha A scan tool is only needed if you want to do the adaptation manually. the ecm will do it on its own. Have you already installed the new throttle body? What is the engine doing or not doing?
+Sasuke Uchiha 1900rpm? Disconnect the battery cables and touch the battery cables together for a few seconds. Reattach the cables to the battery and then start the engine. Same?
Hi there I have an issue on my 95 ABA where idle will slowly go up to 1500 and hang there. I’ve cleaned and replaced my iac, smoke tested the car for vac leaks. Car runs fine but when I have the high idle if I turn car off and restart the problem goes away. Any suggestions?
@@EXOVCDS thank you. My son is a vw tech but he’s at a loss. So if he should try vcds or something to check would appreciate it. Someone else suggested the ufo thing on the throttle body might need to be replaced but mine doesn’t have it. Only other thing I could think of was the EGR might be clogged?
@ChrisHsuCars Not sure, sorry. EGR (exhaust gas recirculation) will lower rpm, not raise it. Does the car have ac? If the ecm thinks that ac is on, it will raise engine rpm at idle. Is base ignition timing correct? Remove the brake booster vacuum hose from the intake manifold, plug the intake manifold pipe / put your thumb over the pipe... does rpm still go higher? Does the front O2 sensor signal voltage vary lean / rich when the rpms go higher, or does it say lean or rich?
@ChrisHsuCars If the idle stays low with the valve disconnected, then it's the ecm that's increasing the speed for whatever reason. I can't remember if there's a PS pressure switch on these. If there is, disconnect it.
Hey Thomas, my 98 mexican golf drop idle at 600 rpm then go to normal 800, stops when i increase the throttle stop screw, but then rpm rev up when i cluth. How adjust throttle plate?
Motorized throttle body? If yes, clean the inside of the throttle bore (around the area of the throttle plate) and put the adjustment back to where it was. Send pictures of the engine / intake / throttle to fkh161@fkh161.ca so that I can see what it looks like. No need if it's a standard production 2.0L.

Hi, a p1128 can it be related to the throttle body? I took my car to the mechanic and he said he did a reset on throttle cause he couldn't find any leaks. Vaccum or fuel and charge me 150 dlls
Cleaning the throttle body & resetting it, is always a good first step... if it has not been done in a while. P1128 is a problem with the air fuel mixture while the vehicle is being driven / not at idle. Since you have already covered the "prime suspects", the only thing that I can think of, is an air leak into the PCV system / engine crankcase. At idle, there is no vacuum to pull PCV fumes from the crankcase / valve cover (because the pcv hose is attached in front of the throttle body). Once the throttle is opened, vacuum is present at the pcv hose that is attached to the air intake tube. A broken dipstick, bad crankshaft or camshaft seal or valve cover gasket... can let air into the engine, that is then routed into the air intake ahead of the throttle body. Even though some parts are new, you'd still want to confirm correct operation. Fuel pressure & flow rate. O2 sensor heater function & signal frequency... MAF sensor signal / load confirmation: (last paragraph in this link) wiki.ross-tech.com/wiki/index.php/Fuel_Trim_Info
The ECM just needs to relearn the normal position of the throttle... the ECM will relearn over a few days of driving or even just letting the engine idle for some time. In some cases a scan tool will need to be used, to reset "adaptations".
Good day Thomas. I replaced the solenoid harness & now I have almost NO power when I put it on drive. It's a 2001 VW Cabrio 2.0 automatic. Last month it was the crank sensor, maf sensor & ignition coil. No matter what I replace it still lacks power. HELP!!

Hello .does work on vw polo classic 1996 1.4L 6N1 engine after cleaning tbd rpm stuck on 2000rpm .i remove the positive battery for 2 min . Rpm stay on 1000 .
In case you missed it... 0:50 to 1:15 battery is disconnected and the cables are connected together with a jumper wire (to drain any capacitive charge). I then reconnected the battery.... the reason for doing this (as title suggests): High idle after throttle body cleaning.
Have you cleaned the throttle body already? Cleaning the throttle body is always the first step. Once clean, let the engine idle for 10 minutes (if you do not have a scan tool to reset the adaptation). If after 10 minutes the engine idle still goes up & down, you can try the battery disconnect method in this video. If the problem is still present after that... you may have a different problem that is causing the up & down idle ( vacuum / air leak, fuel mixture problem, O2 sensor problem etc).
I encountered this peculiarity (and more) after replacing the old throttle body with a less-old, freshly-cleaned throttle body on my 98 with a 99 motor. I just finished following your instructions; idles right and runs like the masterpiece of German automotive engineering that it is. Many thanks!
Thank you for sharing your experience... and thank you for watching!
Thank you! I bought this 98 Jetta last spring, along with a nearly identical parts car, as a temporary car during hard times. It became something of a project for me until a person I loaned it to nearly totaled it in a front-end collision. I've been struggling with oddities since last August and it has been difficult to find good Volkswagen info online. This one short video has provided me with more help than nearly anything I have found in the last nine months. Keep up the good work.

can i just touch the positive terminal with the negative terminal without using those clamps you used?
tanner rubottom The rpm code too low at idle is the result of whatever is causing the idle to be too low (rich mixture, lazy O2, bad MAF, etc). Solve the rich running issue and you will probably solve the rpm code at the same time.
So after you cleaned the TB it went on high idle? What causes it and what did you do to fix it?
I was wondering on my 95 Jetta 2.0 aba, two things....
I have a rather low idle, anywhere from 500 to just under 750,i also for other easons replaced my air filter,and cleaned the maf and the throtlle body, I am wonderring what to do next?
And also I get A LOT of oil in my intake and, air filter, is this due to a faulty pcv?
stupidrelaoded If you have an idle stabilizer to the right of the intake manifold, cleaning the throttle body will not change anything... since the stabilizer is used to adjust idle, not the throttle body.
The intake boot has been redesigned a few years after 95. You can install the updated version that has a PCV heater & vacuum hose, that reduce / limit the amount of oil in the intake.
Go to a wrecking yard and remove the intake boot from a 98 model 2.0 and install on your car.

Hi Thomas, i have an 2002 VW Cabrio, took it to a shop and they say the throttle is out/failing and needs to be replaced. I ordered it and going to replace it by my self. Is there something else that i have to do other than replace the old for the new one? Should it align by itself or i need to use VAGCOM tool?? Thanks a lot
Should be plug & play... the ECM will run basic settings on its own, but using VCDS or similar can speed up the process.

hello there and thanks for the useful video, I was wondering if you knew what was the idle rpm for an 94 jetta 2.0? it's reving like the vw of your video just above 800 rpm
840 +/- 40 rpm with a/c off with a/c on 870 +/- 40rpm your 800 rpm is fine.
Maybe you can help me solve an issue with my mk3 (aba motor) ... bought it for dirt cheap just to flip. And it ran good on my hour drive home but a little cold. Replaced the thermostat and it solved the problem. But the car doesn't want to idle. It won't idle. I will keep dying, also hesitates and jerks when driving. I cleaned out the intake and throttle body (entire intake soaked in oil, including maf) cleaned out the maf and it fixed the issue for about 10 minutes and now it keeps doing the same thing. Any suggestions? Thanks much appreciated.
Motorized throttle body or idle stabilizer next to the intake? Not sure... could be fuel related. There's a TSB that addresses the oil in the intake... install the later style intake tube that has the PCV heater & vacuum hose. If it runs better after cleaning MAF, start with the oil issue.
@ thomas, thanks for the help recently and back to your question with the jetra that has the code p1582 the engine between 805 and 820
idles between 805 and 820 rmps
Did you clean the throttle body bore? No need to remove the throttle body to do so.
Did you reconnect the pinched vacuum hose?
yes I removed the zip tie
going to clean the throttle body one more time using brush and carb cleaner
after checking and doing this what would be the next suggestion
Im a bit confused, so the high idle was the result of dirty battery terminals and dirty connections?
No.
The high idle was due to the fact that the ECM was holding the throttle open in the old "learned" position. As the throttle bore gets dirty, the ECM opens the bore more and more to maintain a correct idle. Once the dirt is wiped away, lots of air can get past the throttle... usually the ECM will "relearn" the new idle setting (will lower the idle speed over time as it learns it). A quicker way to "teach" the ECM a new idle speed / stop, is to disconnect the battery, touch the cable clamps together... this wipes the memory of the "old learned throttle position". I usually use a scan tool, but I made this video to show that it can be done without a scan tool.
@@EXOVCDS if I can’t reach the cable clamps together can I use a jumper cable to connect to each other and just use both positive ends ?
@@ADroneGamer yes.
Hello there I have a lotus exige s with the toyota 2ZZ engine in it and after the mechanic took my TB out for cleaning I have high idle problem @ 1500rpm and takes awhile to drop back down to normal 800rpm..... Help!!!! What u think I can do?????
It might take a bit of time to relearn on its own... I'm not sure if there is a specific procedure that needs to be followed after cleaning (Throttle Adaptation) like on VW & Audi engines. Have you already tried to disconnect the battery and doing a capacitive discharge like in this video? I can not guarantee that it will work, or that something goes wrong. The fact that it eventually does come down to 800, tells me that the ECM has control of "whatever device is used to adjust idle" (throttle plate or Idle valve / solenoid).
This is a great video. i actually took throttle body off my tahoe and cleaned it. didnt move the throttle door much. but now i have 900 at stop light and sometimes when i put it in park it jumps up to 1500-2000 and wont go down. think this will do the trick?
If you cleaned dirt from the throttle bore, you will now have more air flow, which can account for the higher idle. I'm not familiar with the Tahoe Idle Control, but if the throttle is used, then yes, it could help. The capacitive discharge clears "learned / stored" Idle / Throttle positions, the ECM then reverts back to Factory Values. It should relearn on its own, but might take a while.

Hi, i have a 2003 seat Leon 1.6 16v and the revs are playing below 700rpm and its stinks of petrol when you start it but before it used to run with the same problem. Now it starts, idles under 1000 doesn't rev, cuts out when it wants. It's had three throttle bodies on it and all three didn't change the problem. Any ideas ? Could it be the ECU ?
Not sure what it could be... temperature sensor, fuel pressure, fuel pump relay etc. Any fault codes in the ECM?
I changed throttle body but car does not start. It turns over but it’s not catching. Any thoughts on would it could be? It didn’t have a gasket on the old one so I don’t have one on the new one... do you think that could be the problem
Year, make, modle, engine (in case it is not a mk3/A3 VW Jetta / Golf)?
Was it running with the old one? If yes, install the old one to see if it starts again.
There's usually a paper like gasket... lack of gasket should not be an issue.
Have you checked for spark & fuel?
Turn the engine to TDC #1 and show me the TDC marks on the cam gear and on the flywheel / torque converter at the transmission... also the location of the distributor rotor.
You can record & upload a video to your channel and then post the link here, so that I can go check it out. Or, you can click on the fkh161 link in the description and then click "tool request" to send me the images.
The more I know (why did you replace the throttle body / what was the original issue etc) the better I can help.
I can't help if you don't reply.
I just cleaned my throttle body and cranked it up and it idle up to 2500 rpm and slowly started going up more so I cut it off do you what that could be it a 2012 Chevy Malibu
If it's an electronically controlled throttle body, then the ecm needs to relearn "idle". It is still using the old / dirty idle throttle position... which is now clean and allows more air past the throttle (hence, high idle).
The quick way for the ecm to relearn the new idle position, is to use a scan tool that can activate the relearn setting.
The ecm should be able to relearn without a scan tool... just like it learned to adjust / compensate over time for the dirty throttle body. Driving for a day or so "should" give it a chance to relearn.
I drive a 96 Mk3 (A3) GTI 2.0. After killing the battery one day, the throttle began acting very strange. When depressing the accelerator, there is little or no response for a moment. If I hold it at the same position, after about a second the revs will jump to where they should be. The same happens if I manually press the throttle. Idle is just fine. -- Do you think a capacitive discharge would solve this?
A discharge can't hurt, so give it a try. Be sure to clean the throttle bore first or you might end up with a low idle or stalling at idle. If your throttle body is not motorized (only a cable is attached) the issue is not with the throttle. I have a feeling that this symptom is not a throttle issue... see how the discharge goes and let me know. You will have to enter your radio code if still a stock unit.
***** Awesome, I appreciate it! I will let you know how it goes after I try. -- Also, I replaced the PCV and its grommet today, (was cracked and not sealing well) and it seemed to help.
+Thomas EXOVCDS hello, i have high idle 1100rpm after cleaning throotle. Throotle was adapting and have the same high idle. Only when i have first start and when car is cold idle is ok and after temperature is 90c idle go on 1100rpm. I use another throotle but the same problem.

Hey i have a 2007 dodge nitro rt i got the pcv replaced and they cleaned the throttle body at the shop..after that it was in very high idle higher than when i brought it in for them to fix it...the bolt (z) now stays on my dash while driving now never did that before and when at a light or in park the symbol comes on this is draining can you help me out
It could be (just like with these older VW's)... that after cleaning the throttle body, the ECM has a hard time relearning Idle Speed Settings. It should be able to do so "over time"... in some case, a scan tool is needed to "force" the relearn process.
hi, it doesn't work with me the rpm should be around 650-750 but its around 800-900 after
i take the throttle body off i cleaned it without disassembled it i think it should be disassembled the idle air control assembly and clean the valve inside it i think the valve of the isc is stoke - i was replaced the spark plugs with a new ngk bkr5es-11 that recommended for toyota hiace in UK ngk branch i notice after finish the job some drops of water came of the exhaust that's mean perfect burning.
I saw on indetifix you connect the cables for 10 minutes. Is that too long?
Capacitive discharge takes a few seconds... for those who take coffee or smoke breaks, 10min will work fine. New cars with more modules, might require more time... haven't had one of those yet.
Hi i have a problem with vw golf mk3 with AEE engine and after new throttle body and after alignment with vcds car idles at 4000rpm for a 30 sec and this happens only at cold start when its at high temp runs normaly at 750rpms can you help me please
If the engine has a carburetor, you need to adjust the cold start choke setting.
Do u guys ever notice a high idle after replacing a battery or clearing codes on a vehicle with a highflow aftermarket filter? My theory on why that happens is the the car won't start making idle adjustments until hundreds of miles so it goes to a default idle not designed for a high flow filter and that's how u get high idle. Does that theory make sense?
yes this theory does make sense , very interesting
As the throttle body bore gets dirty/ restricts air flow (at idle) the ECU has to open the throttle more to get the correct idle. Once the throttle bore is clean, because the ECU is still using the learned position (of a dirty throttle bore), the idle is higher than it should be, due to the higher air flow. Over time, the ecu should relearn / lower the high idle. The quickest way is with a scan tool or capacitive discharge. Newer vehicles with faster ecu processors can relearn idle speed much quicker.
Hey will a mk3 2.0 run like crap rough idle when I give it gas it sputters no power. Just did the timing belt. Oh btw I broke the pcv valve would that cause it ?
If it ran fine before the timing belt job, it should run the same after... if not, double check what you did.
Depending on how / where the break is... it can affect air flow through the MAF... which can / will affect engine performance. You can block off the PCV where it enters the intake tube (ahead of the throttle) to see if it runs better (remove the pcv hose from the intake tube and block the hole in the intake tube somehow for testing).
hello. I have a 98 jetta 2.0. the idle will randomly sputter sometimes. go down to 500 rpms or so. sometimes it Wil die if I dont give it gas and other times it will go back to normal. it accelerates fine drives fine. and does it hot or cold. There's two engine. code one says its running to rich and the other is rpms to low at idle. any ideas? its had a tune up recently, I have new belts just need time, and there used to be an issue with the coolant temp sensor.
You have probably solved your problem a long time ago, but the solution is to clean your throttle body. That's how easy it is to fix :D I have tried it on two cars with the same problem as yours and it worked both times :)
sir i had the same issue on my civic 07 is it posibble to do the capacitive discharge on electronic throttle body? tnx..
Try it.
I cleaned my throttle body last weekend. It was nasty. After that I got high iddle. Next day I got check engine light. Needed to replace o2 sensors bank 1 and 2. Mechanic told me to clear the codes first because it’s maybe just a fail safe mode. Something like that. I cleared them and The checking engine light hasn’t come back however I still have the high iddle. I tried to reset the throttle body but nothing. Should i try this method?
If you don't have a scan tool that can activate "throttle adaptation / alignment", then yes... this is a quick & cheap way to do it. If the idle is still high after, then something else might be going on. Year, make, model, engine?
hey i just purchased a 2002 vw beetle. After about an hour on the highway, the car stalled and i cranked the car a few times and it started. I drove another 20 mins and it happened again. It does it randomly now and then. What are the isses, i don't think it's gas or fuel pump. I runs great and is arching out from a bad plug wire but is fine. I have to fix that wire too. I've read about the crank position sensor, Idle speed control or maybe my distributor is worm from the arching. I'll clean my MAF but don't think that's it.you've done these cars 100 times over, what do you think. it runs great ,on the highway going 60mph and it just stalls.
+mike shiva Hi... sorry, forgot to reply yesterday! Yes, could be crankshaft position sensor (engine speed sensor). If you have a scan tool and you get a G28 speed sensor code, odds are that the sensor is old & starting to act-up. They are easy to change... here's an old video of mine: ruclips.net/video/LldC6CuXYoQ/видео.html the sensor is located to the right of the oil filter, mounted at the base of the block, close to the transmission.

Hello, i have a vw golf mk 3 1.8 GL, i clean the throotle body, and the car going to high idle, the revolutions move high and down, but the car don´t off. I make the procedure, but don´t work, maybe driving the car for a while, the pcm learn the new condition. The only thing that i don´t know how do it is reset the clock and radio, how i do it? Thanks.
Touching the battery cables together "should" reset the computer... if you still have a high idle, the computer "should" relearn and lower the idle by itself. The buttons in the instrument cluster are used to reset the clock. For the radio, you need to enter a 4 digit pin number when the radio says "Safe". Press am/fm & Scan at the same time until you see 1000, then enter the pin number using the station numbers. If you do not have a pin number for the radio, you will need to contact a VW dealer so that they can give you the pin. They will require the VIN number from the vehicle as well as the Serial number of the radio.
Hey I have a 2011 Silverado 1500 5.3 I cleaned the throttle body because my engine light came on and said “Engine powering down” and I wouldn’t go over 20mph.

hi,,,,does this car have a iac valve ? where is it located ? thanks
No... this engine / year of 2.0L ABA does not have an IAC. The ECM adjusts the position of the throttle plate to increase or decrease the engine rpm / idle. 2.0L ABA engine from 1994 to 1997 used an IAC valve... located to the right of the intake manifold above the valve cover.

Check for vacuum leak... the rubber flange under the throttle body and the vacuum hose (at the intake manifold) that goes to the brake booster.
@@EXOVCDS if it not has wacum leak can the reset help
Don't know, maybe. Can't hurt to try. The reset is mainly for 2.0l.
Will the ecm relearn without battery method?
Yes it should... the "capacitive discharge" method just speeds up the reset, just like a scan tool can be used to do the reset.

Hi there I have an issue on my 95 ABA where idle will slowly go up to 1500 and hang there. I’ve cleaned and replaced my iac, smoke tested the car for vac leaks. Car runs fine but when I have the high idle if I turn car off and restart the problem goes away. Any suggestions?

Someone else suggested the ufo thing on the throttle body might need to be replaced but mine doesn’t have it. Only other thing I could think of was the EGR might be clogged?
@ChrisHsuCars
Not sure, sorry.
EGR (exhaust gas recirculation) will lower rpm, not raise it.
Does the car have ac? If the ecm thinks that ac is on, it will raise engine rpm at idle.
Is base ignition timing correct?
Remove the brake booster vacuum hose from the intake manifold, plug the intake manifold pipe / put your thumb over the pipe... does rpm still go higher?
Does the front O2 sensor signal voltage vary lean / rich when the rpms go higher, or does it say lean or rich?
@@EXOVCDS no AC it’s a base car. Has a chip, adjustable cam gear and intake with exhaust if that helps.
@ChrisHsuCars
If the idle stays low with the valve disconnected, then it's the ecm that's increasing the speed for whatever reason. I can't remember if there's a PS pressure switch on these. If there is, disconnect it.

Hi, a p1128 can it be related to the throttle body? I took my car to the mechanic and he said he did a reset on throttle cause he couldn't find any leaks. Vaccum or fuel and charge me 150 dlls
Vw new beetle 2.0 1999
I've changed the fuel pump, o2 sensors, MAF, air intake tube, vacuum hoses
Cleaning the throttle body & resetting it, is always a good first step... if it has not been done in a while. P1128 is a problem with the air fuel mixture while the vehicle is being driven / not at idle. Since you have already covered the "prime suspects", the only thing that I can think of, is an air leak into the PCV system / engine crankcase. At idle, there is no vacuum to pull PCV fumes from the crankcase / valve cover (because the pcv hose is attached in front of the throttle body). Once the throttle is opened, vacuum is present at the pcv hose that is attached to the air intake tube. A broken dipstick, bad crankshaft or camshaft seal or valve cover gasket... can let air into the engine, that is then routed into the air intake ahead of the throttle body. Even though some parts are new, you'd still want to confirm correct operation. Fuel pressure & flow rate. O2 sensor heater function & signal frequency... MAF sensor signal / load confirmation: (last paragraph in this link)

What u think????
On my 2.0 mk4 goes high then comes down will this fix it?
Have you cleaned the throttle body already? Cleaning the throttle body is always the first step. Once clean, let the engine idle for 10 minutes (if you do not have a scan tool to reset the adaptation). If after 10 minutes the engine idle still goes up & down, you can try the battery disconnect method in this video. If the problem is still present after that... you may have a different problem that is causing the up & down idle ( vacuum / air leak, fuel mixture problem, O2 sensor problem etc).
Did you try it?
