Thanks for this information! Excellent video
I AM SO GLAD THAT I FINALLY GOT THIS ANSWER!
After 7 months of driving my 2012 GMC Acadia and it driving fine one day and then having all of these issues the next... its nice to have a clear answer for once.
Mine all started with a "Service Stabilitrak warning" and "reduced engine power". For some reason, the shop/dealers are useless and couldn't figure that out for me.
Its nice to hear from you ☺️
Very helpful i love how everything was broken down😊
I completely removed the traction control buttey and then ported and polished the excess room I had available under the main throttle body.
My throttle body also makes this fluttering noise usually when it's cold but even when the engine is hot to. I also have all the other symptoms mentioned in the video.
Would it get louder as you accelerate ?
@@offroadracer2136
Yes, and I actually replaced it with a new one. It's still make the same noise as I accelerate...
The symptoms you describe are related to the throttle position switch . Not the throttle body.
Thank you
My car is throwing the code for the ECM, I've gotten my starter & alternator both tested and replaced the battery. It's wanting to start but the flap on the throttle isn't working. Do I need a new throttle body? (I'm very guilty of riding on E often)
Video helped changed my throttle body today
Glad to hear from you my friend.
Need help, My Chevy Cruze petrol, just having rough idle and a lot of white smoke, the mechanic already change the Piston ring, cylinder gasket, but the problem still there, help me diagnose the problem, is it air flow sensor, or bad injector, or bad coil, or bad head gasket or EGR valve? Thanksss
THANK YOU!!! bro I have been beating my head I to my car trying to figure out why my roms jump and why my car will not accelerate while driving and then give me full power 2p seconds later. now I know
Glad to hear from you brother.
Will this cause your car to smoke white a lot?
Thanx
I love this
Thanks mate
yo can anyone tell me what’s wrong with my 02 celica gt, i launch it and forgot to pull the ebrake down and the wheels kept spinning and after, it feels and sounds rough when turning it on and when reving it and when at low rpms
I have none of these issues but got an error code. So I changed out throttle position sensor. Hopefully engine light goes away.
What might cause 2010 Tahoe to reduce engine, stability tracking to come on. Replaced throttle body, floor pedal, reprogrammed ecm sensors
I just got my throttle body done and now my car rough idles n shakes da mechanics not open on Sunday what they do to my car
My VW GOLF MK6 2.0 TDI shudders/shakes when I turn the engine off, no other problems, could this be a fault throttle body/ASV?
I have a 350z and my lights came on showing me service engine at first then my slip n traction control lights came on. Lost power to my car so I pulled over turned off the car n back on, it was fine to drive after that and only the service engine light was on. I just got the car when I first noticed something strange some white smoke coming out the exhaust. And it idles high but i didn’t think anything of it because it was a way better car than my last.
Hi there, as there's a check engine light, could just scan for fault codes....
I have a 15 5.7 charger rt and this week my car started acting funny and it lost power and whenever I’m in paddle shifters mode it will go through first and second find but sometimes at third it shift automatically down to first and not to long ago I was in first trying to shift up to second but it said shift not allowed may this be a bad throttle body?
I have a 2006 GMC Sierra andI got the throttle body fixed because the mechanics computer said that's what was wrong. My truck was acting up as I excelrating my rpm was moving up and down only when going from 30-60mph and could hear an engine rev soun everytime it did it. I ended up getting a bead new throttle body put in and it still does it. Also I just got the purge valve fixed because it does a rough idle everytime I put gas in. Do you think maybe the throttle body is what was wrong the whole time maybe not being put in right. It's still doing it after a new throttle body and it does idle after gas anymore. Do I need to get the throttle body looked at again or something else. Thank you
A jumping rpm can be a reason of crank angle sensor or even transmission slipping can too cause especially im auto. If you have a wire drive accelerator pedal, the potentiometer could also do the same which messes the throttle body up. Have to diagnose it properly and professionally.
Sound like all the problems my car is having plus the eml light comes on and she shut off when I’m at the light
My idle is horrible and I’ve taken the throttle body off and cleaned it but it keeps jumping from 500 to 1000 and the car starts to shake real bad until it finds that perfect medium of 700-800 rpm and somtimes stalls like it chokes it self at a red light
Hi there, you might be having. 1. a block at exhaust or intake, 2. throttle position sensor failure, 3. dirty intake air metering sensors.
Check your sensors
Crankshaft sensor?
Clean your MAF and IACV too.
Check the ground wire. I had a bad ground to a MAF sensor plug and it caused issues like that. Oddly it didn't produce any error codes either.
I did cam swap but mine truck stalls when parked It losses power.
E46 2003 , does the bad throttle body brings the eml light on ?
Yup absolutely it will show a CEL if throttle body has a problem. Mostly when tps has an issue.
Can this cause a Nissan Maxima to go into limp mode. Or pressure issues with the transmission?
If the engine goes to limp mode, its mostly bcs of engine malfuction and not transmission malfuction. There are many reasons for the car to go safe mode. Its a good idea to scan the vehicle first so to get the fault code stored by the ecm.
Yes to both, it can cause your vehicle to go into Limp Mode, and it can play around with your transmission causing a jerking feeling, or slippage.
I have a question!
thank
Glad to hear from you..
Could some of these symptoms be the same if it were the Catalytic Converter that is messed up or clogged?
if it's clogged, you might see low top end power from the engine.

Hope you could shed some light, as i step on the accelerator pedal when AC is not "ON" and release it there's some kind of lag as it decreases its RPM between 3k and 2k but when the "AC" is on itgies nkrmal withoitany lag, do i have abad throttle body?
Hi there, delayed deceleration can be a symptom of sticking throttle body or idle air control valve. This can also happen if the evap system has a leak or even a vacuum leak.
@@autoinfogroup1629 thank you for noticing me 🙂. Its a brand new car and it has 25k mileage. Is it normal to have that symptoms for an early mileage? What is your recommendation ?
Yup I have vauxhall zafira 1.9 and I was driving on the motorway soon as I got too 70mph I lost power and spanner symbol came up. Now before this the car been acting strange where the revs going extremely high before changing gear and sometimes I have really put my foot down to get the car going. Just had rac out they said it's the throttle body I don't know how too clean it or if it's just worth buying new part 🤔
Rpm going high is good sign of throttle position sensor going crazy or there's a vacuum leak somewhere. As the check engine light came on, could just scan the car to get the codes poped up.
@@autoinfogroup1629 codes that came up DTC: P0380,Glowplug, control circuit
DTC: P0001,Rail pressure
DTC: P1125,Throttle actuator
@@autoinfogroup1629 guessing the rail pressure caused by the throttle?
Fuel rail pressure cannot be an outcome of throttle actuator or vise versa. Cant say that bcs of electronic controls. The rpm going high is because of throttle and the power restrictions may be of the fuel regulator. Best will be to clean the throttle body first as the dirt can sometimes cause valve stickiness so it wont shut properly. Do it first before swapping parts and see if anything changes.
@@autoinfogroup1629 thanks
Hi, my audi a4 b7 intermittently goes into limp mode only when slowly accelerating from a stop. Car doesn't go into limp mode at cruising speed. When light turns green i just lightly pressed on the gas pedal and it goes into limp mode. There are no check engine light or codes. Any help would be greatly appreciated. Thanks
Did u ever figuered it out
07 5.3 Chevy. Either my mafs is out or my throttle body how can I tell the difference or is there any.
Just unplug the maf and drive..see if the car becomes better. If yes then surely it's the maf sensor.
How can I solve my problem with Isuzu axiom petrol v6 engine on bad throttle
Hi there, you haven't mentioned the problem yet.
Cleaned throttle body with the throttle body spary now my rpms are moving in park?
Might have messed up TPS or there's a chamce for vacuum leaks. Try calibrating the sensor manually n check for loose clamps or broken pipez
So the truck will do fine when going through gears. But when I stop at a light or stop sign, it doesn't want to go anywhere. I literally have to press the gas pedal all the way down. It's a 1999 ford f550. Please help
Do check the throttle position sensor.
@@autoinfogroup1629 I sure will Thanks!
My car shuts off when I turn my A/C on. Could a bad throttle body be the cause?
May be... any air restriction like throttle body clogs, air filter, sensor damages or fuel restriction like clogged fuel filter, failing pump etc.. can cause the issue. also a bad crank angle sensor. Should go through each one to resolve.
My cold air intake came off and now my truck is back firing and running super bad, is the throttle body trashed?
may be... give a good look at the intake side.
@@autoinfogroup1629 so maybe the intake is bad?
How can I recalibrate the throttle body
check on google
Will this cause car to feel jerky, rpm going all over with random burst of acceleration. Also won't start without letting sit for a few minutes
Throttle body does make the rpm variations and engine runs rough. A faulty crank sensor too give same symptoms with starting issues. There are other reasons too. Can say unless its diagnosed properly.
This sounds more like a fuel pump honestly
Check fuel pressure regulator if its a dodge do the key jingle for hidden codes
I'm having this exact issue word for word on my 2013 bmw 535i, I really need help , I change da MAF sensor , spark plugs coils, da lil pcv valve and I'm about to change my valve cover . Is it throttle body or fuel pump???
Crankshaft sensor?
Can this cause a 'slipping sensation' between gear changes in an automatic? I have a strange rev hang from 2nd to 3rd but gearbox seems fine.
I guess not. As a preventive you could just clean the throttle body n air intake sensors.
yes it absolutely can. "I guess not" is not a professional answer. If your throttle body is very dirty, or actually damaged it will give you power loss, and it will prevent you vehicle from gearing normally, causing a slippage sensatiion, or you might actually feel the vehicle jerking. Hope this helps.
Din mention the power loss. If there's a huge power loss he must have noticed that too. And its tru if vehicle does not produce power gear shifts go rough.
Yes, my 2010 fusion felt like the tranny was slipping. Put on a new throttle body and it worked fine.
Interesting....same here. Slippage feeling between 2 and third.... Also vibration in idle (mostly in D/R engaged)....
My car struggles with acceleration after 2000 rpm. Could this be the throttle body. Everything else is ok. Idles fine. Thanks
Hi there, this could be throttle body also this may happen if there's a fuel restriction ie, dirty fuel filter or failing fuel pumps. Replace the air and fuel filter if too old and give check on throttle body, air intake sensors and fuel pump or fuel line pressure.
@@autoinfogroup1629 I'll check on those. Much appreciated 👍🏻
Any time mate :)
Have stories like this from friends of mine, if the issue triggered by certain RPM or velocity, that could be caused by the valve timing issue too.. commonly the sensor
So if the throttle body is fixed. Will the engine light not be there anymore
What makes the Throttle Bottle Light Stays On???
Will it stop the car from starting
A chocked throttle body cause starting troubles but may start with slight press on acceletr and also will stall when released.
Could a bad ecm cause this to act bad?
Yes it could act wierd!!
My revs drop very slow when reving in neutral or changing gears while driving Can that be bad body throttle ??? Please help
Could be the throttle body especially tps or pedal position sensor. There might be other reasons but mostly related to revs comes from these units.
So is it better to buy a new one or just clean it ???
For old models with cable, just a clean up does the job...new gen motorized needs a thorough checkup..if its too dirty clean em and if the problem reappears might need a replacement
@@autoinfogroup1629 well I got a Lexus is 350 2006
Is a throttle body and a throttle valve the same thing??
Yes both are same...throttle body is a kinda of valve.
Haveing the same problem...but no light on dash..anyway forward
Hi there, pls do mention the specific issue you are facing.
Hesitation...soting.and rough idleing cut of when ac on...transmission dragging on in third.
@@garyhews did you ever figure out the problem? My car is doing the same
Can bad throttle body cause backfire?
Yes if the flaps are not calibrated properly can cause backfire.
@@autoinfogroup1629 okay thanks
Any time mate
Throttle body dont open up when accelerating
Might be a bad thorttle body motor if electronic or a bad pedal or the cable might be broken if mechanical.
What causes the throttle body 2 keep flooding
It should be the carburetor type. More commonly when the float or the float needle goes bad, causes the flooding. There re other like, if its a electric pump fed carburetor, a bad regulator can cause the similar issue. If the airfuel aduster is not calbrated properly, if the fuel orifice has a problem. If there's too much pressure inside the fuel cavity inside the carburetor. If the seals in the housing has cracks or leaks or a vacuum leak.
I like my Ford generally but I have replaced this throttlebody four times. It’s a piece of crap. Ford should’ve taken care of this for the money we pay for these trucks. I don’t think I’ll ever buy another Ford.
Ford throttle body needs constant calibration and positioning...and sometimes its a head ache...but once its in shape...ford engines makes good outputs...
Bro I just took it off sprayed it with carburettor spray and put it back
Yup that should clean the valv
Peugeot 1.1 why won't the apostle above 3000rpm show me
Sry.. pls be specific...
My car makes noise between the top and the throttless body, am confused
Multiple misfires
Why the weird English sentence structure?
Are all mechanics just a fake voice now? If so…I’ll figure out how to fix it myself.
That's just stupid. You're gonna let your pride/ old fashion way of thinking get in the way of taking in knowledge all because you don't like the "voice"?
Quite alot of effort to produce a terrible narrated video. The eighties called and want their robot narrator voices back.
What if there's oil going in my throttle body?
