I have a 2002 polo classic, I tried all options but it seems that car has ghosts in it. The car is giving fault codes of bad map sensor. I replaced it first with an after market product, didn't work so I bought the very unreasonably expensive vw part..and the car won't even start anymore with I plugged. With the aftermarket sensor it starts but it hesitates when accelerating. Please help with any advice Scotty..I'm in Namibia by the way. I love your videos so much.
Help me please to figure out the problem in my jeep wrangler 2014, 22000mi , seal was broken between Cadillac converter and engine black, fule consumption was 13 mpg after new seal same mpg ,I reset computer by tuching
- + wires and got 18 mpg local (wow) 4 days later I drove 85 mph on highway about 30 minutes when I got off Highway jeep was vibrating , idol was low and make noise when push gas, RPM doesn't go up unless I push hard , I will be thankful to you like before you helped me .
Scotty Kilmer I
I have a 99 Plymouth Grand Voyager . It was running fine and all of a sudden wouldn't accelerate. I cleaned the throttle body and it still runs rough.
Scotty Kilmer
Wish I had a handy uncle/dad/grandad like you Scotty.
Or father-in-law
I wish we all did
Uncle Grim what about yourself you should be a handymen
My great grandfather and grandfather (moms side) was a true handy man. Never met them... :c
For his info alone would be priceless. He is one of the best.
Scotty you have saved me thousands of dollars over the past couple years, i owe you a big thankyou. And keep it up, thankyou again.
He accepts donations... maybe, lol
He saved you thousands of dollars. In return, you said thanks ? Good deal !
Maybe buy him a gift ya cheap fuk
I love how the cop sirens start going after the alarm haha
This video was perfectly timed... I developed a low idle problem recently in my '05 Chevy Cobalt (140k), especially when coming to a stop. I pulled the throttle body and gave it a good cleaning, and she was good as new! :-) Thanks Scotty!
Just did this to my car just now. Everything worked perfect. You specifically want to do the re learn step at the end so the car idles normally. Great video Scotty!!
I watch videos not even related to the diy advice I'm looking for on my charger just because theyre that informative and insightful, good to know auto facts
I just clean my girlfriends throttle body on her 2005 Acura TSX and the rough idle/surging is gone! Thank you Scotty for giving us the knowledge and encouragement to get the job done!
just did this to my 08 TSX and it made a world of difference i was having the idle drop when breaking at stop lights or when shifting into any gear it dropped idle to like 600 this keeps its at a nice and steady 850 - 900 ish its feels way smoother
Thanks Scotty. I've been watching your videos for about a year or so just for entertainment, and this is the first video of yours that I have watched to learn the repairs.
thanks man,I got the cleaner spray. Took The throttle body out and cleaned it. it works great now. keep up the good work
Do you have to buy the throttle body spray or would WD 40 work
@@joshuaspencer4272 only if you remove it from the car. I bet gasoline can probably work just as well. Make sure to wipe it clean afterwards
Anoop Singh ok thanks
@@joshuaspencer4272 buy carb cleaner. Wd 40 is water displacement it could work but that's not what it's for
On the next Scotty Kilmer episode, I'll show you how to level your headlight, but not before I deliver this baby,
lmao the endings are so random but cool if you think about it
Mr Scotty my Audi b7 2005 rpms go up when I drive and came to a stop help please
Scotty knocks up lots of hoes!
Thank scotty! Cleaned my throttle platte, car was idling rough en was jumping between 500-700 rpm with A/C on. Now runs perfect on 900rpm! Kia Rio 1.2 CVVT easy diy!
Wow, I did the same job on my accord 07 and it actually solved the idling issue on my car, before doing the throttle body cleaning whenever I put the car in drive or turn on the ac , the rpms drop which resulted in the vibrariin. After cleaning it the car rpms have improved from 650 to say 850 while idling and no vibrations, secondly after this whenever I turn AC on , the rpms just increases 100 for a second and comes back to 850, and no vibration. It feels perfect and even driving I feel more power in my car with getting better acceleration output speed. Thumbs up to Scotty .... You rock 👌
While looking at your videos , i got a smile on my face.......................every time !
Thanks Scotty.
Thanks for this video. I just did this to my 2005 Corolla, and it fixed the low idle vibration. I am very pleased now.
I appreciate you keeping the alarm blaring when the negative is back. No edits, my man
Thanks Scotty! My 96 civic was idling poorly when I had it in neutral and at red lights. and sometimes I was worried the car was going to die because of how low the rpm was.I did the same steps as your said and now my civic idles right below 1rpm and it drives amazing! feels like I actually have some torque now.yes i know its a civic but still..and it picks up speed way better than before ..before every time I shift into gear and gave it gas it seemed to pudder and the throttle didn't respond well. thanks again. cost me about 6 bucks at the O'Reilly's
Thank you! Now I can clean it myself!! I’ll update if it works 😬 fingers crossed 🤞🏼. Update: MY CAR RUNS PERFECTLY NOW
I’m going to try this tomorrow
How was it running before?
This is so amazing..... I googled "how to fix a low idle" i clicked on this link NOT KNOWING you were gonna fix a toyota corolla that just had it battery changed. EXACTLY WHAT HAPPENED TO ME AND MY CAMRY YESTERDAY. I have goosebumps and chills with the hair on the back of my neck standing up. So many thanks Scotty!
Scotty I have a 2003 Corolla with 206k miles. I started to have problems when I came to a stop while idling my car would shudder and drop to about 200 rpm or less. I found your video ( already a subscriber) . I did exactly what you showed in the video and I have not had a problem since. Thanks for the tips!
I've also found it helpful to remove the Idle Air Control (IAC) and clean that really good when cleaning the throttle body. Great Video!
If you take the hose off thats connected to the iac to air duck. Stick a funle in it and dump seafoam gradualy it fixes iac issuis
Sir scotty i learn a kot from you.
Thanks
Thanks for helping me save money. You're the man. I respect your willingness to give us information for free when we all know that many others won't even dream about sharing with us their tricks of the trade. Again thank you and you're greatly appreciated.
Changed a battery in my 2010 Corolla and when it idled funny I knew exactly where to go. Thanks so much for the help Scotty! It's running like a champ now
Thank you for helping me fix my car. You are so knowledgeable as well as fun to watch! Spot on! You are my go to when I need my car problems solved!
You are the best my friend. I salut you from US Naval Base Japan.
Crazy-ass Scotty! He's the best!
Scotty, I've really enjoyed your videos!
Currently converting my XJ650 Maxim to EFI. Having a lot of fun tinkering around with it. The tools you show on your car videos really have helped me on my motorcycle already.
You helped me figured out why my 2004 Camry wouldnt turn on for me after I changed the gasket with your videos ! And to find out it was just a dirty throttle body and filter .now with no leak and running like new again ! Thank you so much !
Awesome! Makes me want to get out bed and tinker with the cars problems vw polo 1996 :-)
I just did this in my 2010 crv. But I didn't push the throttle manually, in other channels they say u have to turn the ignition on and have someone press the gas pedal. Other wise u might break the some thing in the electronic throttle. What the right way Scotty ? Love u r videos brother.... Best wishes from NYC
You are correct. You don't want to manually manipulate an electronic throttle body. Doing what you did is the proper way.
NEVER do such cleaning with the car on, notice I disconnected the battery doing this. Any throttle can be opened by your fingers or a wooden tool so not to scratch anything.
Scotty Kilmer Hi Scotty. Actually if you open the throttle body with your fingers don't you risk ruining it? I've heard that it will burn the motor in the throttle body on newer cars. Also it has enough force to clamp shut and take your finger off.
Cragified is this why my car tripped code p2118?
Unlikely. Unless you forced the throttle plate open with the key in the run position. Or forced it open against a mechanical resistance.
These are the most common causes of the P2118 code:
Poor electrical connection
Open or short in the actuator circuit
Throttle actuator control motor failure
Failed pedal position sensor
Throttle position sensor faulty
You can have a view of just Scotty’s head and you still can’t go for 3 seconds without seeing his hands. Lol. I love it. Great video
super enthusiasm you've got there man :) in fact, you made it seem so easy i went ahead and pick up a can of throttle body cleaner and did it myself. keep it up man. your enthusiasm is reassuring.
Best to remove the throttle body (only takes a few minutes more) and thoroughly clean front and back of throttle body plate. And be careful, jamming your fingers into that throttle plate can mess up the throttle body motor that's on the side.
I really wanna do this because i saw the inside of it and it looks nasty.
Oops, I push my fingers in it now it's rough idling. Now what do I do?
a toothbrush with hard bristles works magic
This is perfect, just what I was looking for since I have a scion Tc '05 and I've been having this problem for quite a while, guess I only need to look for the spray now since I didn't like the idea of removing the whole throttle. Thanks Scotty!
Thanks Scotty , your videos help me to clean my throttle body and now my Scion tC runs smoothly. God bless you
I have a tc as well what did you disconnect in order to clean the throttle?
You should do one for a car that over idles and drives itself my car does that I need help !!!
johnathan lopez check the throttle cable if it's an older car; if it's newer it's the computer that controls the throttle
automatics do that. please do not reproduce
If you disconnected the tps sensor connector you may need to do a tps relearn

Thank you! After my battery died from the deep freeze this year in Chicago, my highlander was shaking and shutting off when idle. Thanks to this vid i was able to fix it. Now to find out why my engine has a tapping sound...
Just my exact problem. Shaking after battery change. Now I know what to do. Thanks Scotty.
THATS WHY I OWN A OLD CAR THAT ISNT INJECTED AND IS VERY EASY TO WORK ON AS ITS ALL OLDSCHOOL MECHANICS THAT ARE GOOD AND SIMPLE LOL !
GOOD FOR YOU MATE, IM SO HAPPY FOR YOU.......... WHAY ARE WE YELLING??
Man you guys are all idiots
tom miller and you're the genius 😂
wow the things u can do without kids.
fix your car?
Wat?
+Alex M shes trying to say if you have kids you cant do anything else
That's what I done thunk he/she said...which brings us back to...Wat? lol
lol im a guy and yeah Joshua youre right.
Love your videos Scotty! Fixed low idling on my Corolla with this video
Scotty is the BEST online mechanic period.
i wish scotty kilmer is my dad.
If he's your dad, you will not appreciate him.
You can't do a repair on a Toyota poor idle without checking the IAC! (Idle air control, most common cause of idle issues).
The dirty butterfly valve/throttle body doesn't affect the idle on these engines unless it's stuck slightly open, causing fast idle issues instead of low idle.
You need to start by removing the IAC from the throttle body and clean it with carb cleaner or similar. Then use wd40 to free up the shuttle inside. This shuttle rotates to create an air passage that bypasses the butterfly valve and allows the engine to run while the butterfly valve is closed. (This is why dirty throttle body issues don't cause slow idle)
They can suffer from a carbon build up that causes them to stick in the position they sat in while the engine was warm but this is no good when the engine is cold and requires more air to run smoothly. This is why the problem only persists when the engine is cold.
You should also do a simple vacuum leak test before taking anything off the car so you can eliminate vacuum leaks as a cause. The rubber gaitor that attaches the MAF to the throttle body on these engines is a common failure and would also give issues with erratic idle.
It's an electronic throttle body it doesn't have an iac
1998 Toyota Camry. This is exactly what’s happening to my car. I haven’t found a leak and I’ve cleaned the valve. I might’ve missed the butterfly valve being stuck I think I noticed something like that but I have very little knowledge when it comes to cars
Electric throttle body uses a (TPS) throttle body position sensor to control the idle and throttle valve position.

Man I love this channel. Fixing all my problems. Thanks tons!
VW Polo with low / poor idle. Followed your instructions - no problems running well. Thanks alot
You should have taken the throttle out of the car first and then clean it up, otherwise, all dirty stuff would get into the engine.
I have been cleaning throttles for years.
HI Radhy, my car ,Renault Megane 1.6 ,as a electronic trottle and somebody told me not to finger open the butterfly trottle when cleaning as it can upset the sensor, is it true? Thank you
@@pauloisidoro2 you should put the car on without starting the engine and your friend must push the gas peddle in. Then it will electronically open and you can clean it without using your finger.
THANK YOU SO MUCH!!!! Same problem with my 2002 Toyota Camry. It was idling so low it was cutting off the engine, if it wasn't for this video idk how much more money and time I would have to keep spending, again thank you so much for ending my stressful weekend, I'm ganna drop a subscription man
Your videos are great! Thanks for making them, you've saved me hundreds of dollars!
Wow Scotty you were still a youngster back then! Your advice is still helping me out today
Hi Scotty,
Just a follow up on the issue with my 01' AU II ford falcon. I have replaced the throttle body with a used one i picked up for about $60 and the car has idled perfectly since. Thanks again for your help :)
Thanks for the quick reply Scotty. Really enjoy your videos.
I ALWAYS saving money with SCOTTY's videos!!! Thank you!!!!!
Thanks for the tips. Gonna try to fix my rough idling.
Hey scotty. Just want to say thanks.
I did as u said and cleaned out the Throttle Body. It runs like a beast again!
thanks man,I was having the same problem with my 09 corolla. it works better now. Been looking for the Mass airflow sensor cleaner but no luck.
It worked!! Thanks Scotty! I have a 2011 Toyota Sequoia and had just replaced the battery. After I replaced the battery, I started the vehicle and motor was very quiet couldn’t tell if it was on. I started backing up on my driveway and it turned off. I turned it back on and drove to gas station, again it turned off as I was turning into gas stall. I wondered why just changing the battery would relate to this problem. Well looked up info on RUclips and found Scotty Kilmer’s video. Did just like he said to do, cleaned out throttle body, test drove vehicle and now running with normal idle rpm. Was about 500rpm after battery change, then about 1,000rpm after cleaning throttle body.
Youre one of my favorite person in this world 🤙🏾
Scotty, first I love your videos..... I cleaned my throttle body on my 98 Toyota Celica. I have big hands... you know what that means..... big fingers too. So it was a little difficult to get my fingers in enough to really clean. Other videos suggested using wire brushed or old toothbrushes. I thought the wire might put grooves in the metal so I used a toothbrush. I found wrapping an old t shirt around the toothbrush and soaking the material really helped to get in there and remove the grime. I still rough idle a little when warmed up but not like it was before. Thank for the videos. You are great.
Loved the horn going off at 2:20. Those are the moments that make you want to cuss and beat your car with your wrench.
You are the man Scotty! My Toyota is running great. You saved me about $250
Thank you!!!
That fixes my car problem!!!
This is one thing for me to look into. Cheers for the video.
My car was sitting for 2 weeks and when I went to start it up it was running and shaking with low RPMs like it was missing or running on 3 of 4 cylinders. After a while it started to run fine. I've checked the plugs they all look fine. It does it at random times like once every few weeks so It's not constant and very random but with the above video in mind I'll check the airbox.
Hello man, have you found the problem? I’m kind of experiencing the same issue at the moment
whoa, what a great part-time job sir scotty!
love it awesome having a guide to illustrate cars personality with all that technology inside thanks a million. Scotty you demystify car behavior.
You have saved me ALOT of money and headaches,thank you🙋
I just want to come on here and say this, I have had several mechanic shops try to screw me out of tons of money being a single mother I’m not trying to be mean or anything, but I think some of these people just try to take advantage of women. That being said, I have started watching your videos several years ago and I’ll have to say you have helped me a lot, sir, and thank you for that!! 🙏🌻 and I tell everybody about your channel and I tell them to check Scotty first 😂
Back when i had crown vic she was idling low and the mechanics drove me crazy they changed oil pump and spark plugs and coils ! But the problem was not fixed yet , after one month one guy cleaned my throttle and the idling problem was fixed ! I wasted so much money on unnecessary parts change , i know changing them is a must but not in that situation. Thanks scotty😍
did this last week to my subaru 2008 ant it works like a champ now. My KN filter was so dirty i has to give it a wash 4 times till the water wasnt muddy. Thanks Scotty!!!

0:37 dashed my hopes and dreams. I did fix my idle problem though. Thanks.
Scotty you are the real hero..
I learned a lot from you
Loved the Burglar alarm going off. Added a bit of realism to the video.
that makes alot of sense I just changed the battery on my Scion xB and it's idling poorly I hope this works
Doing that tomorrow in my Saturn, changed the air filter today and discovered that the throttle is worse than that cars by a million times! Thanks for the advice.
Wow i had the same problem.5 thanks Scotty
Ok thanks scotty I do remember a spark plug coil spring coming apart but I just put it back thinking it was supposed to do that ill look at it and replace it and ill see if it fixed it thanks again
This video save me a lot of Money!!! ThAnks from Dominican Republic.
What a GREAT video Scotty! THANKS AGAIN!
thanks.; i doing same thing to my daewoo lanos during 5 years by myself. but i also clean inside not only cover. all work perfect.
I have 88 f150 put on brand new iac valve and was having same issues will try and get back to ya thx for tip
Scotty Kilmer the force is strong with this dude
I had a stalling 00 Silverado but this worked great!
thanks Scotty, worked beautifully and saved me some money
I will test this on my 1999 Volvo V70...Thanks Scotty
Amazing guy. God bless you scotty. Love from Pakistan
I have learnt So much watching your videos thank you Scotty 👍

I LOVE YOUR CHANNEL
Sweet gonna try this on my ford escape 2004 model, i thought it was my rocket gasket cover seals being the problem (which they did leak a bit of oil onto the spark plugs) so fixed that but still got that low idle issue, gonna give it a clean like in this video and see how I go.
thx for the quick video, i got a 2012 vw jetta s 2.0l.
While i was driving the check engine light came up and i got a epc light
The check engine codes were to some of the cylinders and ignition coil a primary/secondary
So i changed out the spark plugs and wires, cleared the codes and it was good for a couple days till the check engine light came up stating the same codes..
Also, the epc light comes on every now and than driving it after an hour or two and what it does is it lacks acceleration power, and i cant get passed 50mph and the shifting kinda jerks
This problem only happens when the epc light comes up.. so im gonna try this and hopefully get a new coil pack module and possibly a new throttle body..
I'll keep ya updated hopefully this cleaning keeps it good for atleast a couple weeks.
I think I'm going to cry. Thank you very much!
My 2010 Corolla only has 74000 miles on it. The battery was dying and I knew it. Then it finally went dead so I got a jump and went to auto zone and bought a new battery. It has been idling poorly ever since. It idles fine in park. Nice, smooth and quiet but drops to about 600 rpm in drive. And in reverse, it shakes and feels like it is going to die.
i love this channel!!
thanks bud! hope this works for me too!
