How to Fix a Car that Idles Poorly (Rough Idle)
Does your car idle poorly, have a rough idle, or in general have an idle problem? Learn how to fix a car with high or low idle, and learn how to fix a car that idles up and down by cleaning the idle air control valve. The IAC valve is what keeps the cars idle at around 800rpms. If you turn the ac on and it idles low or your car stalls at lights or in reverse, or your car shakes at idle, this video can also help!

hi all i have a Vauxhall zafira mk1 1998 she fluctuates on revs above idle and is chuffing a fair bit of while smoke the fluctuating issue failed its mot on emissions any ideas thanks
i have a 2007 dodge ram 1500 and it starts but i have to keep my foot on the gas or it will die would this be an idle problem
My car did this. It idled either too high or too low. These days it fluctuates between 500 and 900 rpm. Up and down up and down until it just stalls. I cleaned my idle air controller and it worked amazing for a month. Now it's doing it again. What to do now?
What do I do if I have this issue with a carburetor
Hi Chris, Would you recommend cleaning the inside of the throttle body?
rpm not rpm's
any idea why my car shakes, vibrates, poor idle only when cold?
Do you still drift
How could anyone dislike these videos they’re meant to help and educate just cause you can’t find something doesn’t make it invalid why are you hating or they’re your competing channels and they suck and they want to bring yours down to bring theirs up but you’re the man bro
So I have a 2019 Ford F150 XLT and this made me want to search for the part and clean it even though it doesn’t need it this guy makes me wanna go to my car and start fixing shit that does not need to be fixed you are very dangerous but very educational i learn so much from you
dislikes are from the people who are trying to fix their iac in a tesla
[Neighbor hears a bunch of commotion going on outside, peeks out window] [ChrisFix in the background just screamin and yelling in excitement, talking to carparts while holding a huge camera and grinning from cheek to cheek]
OMG. 2014 maserati.. sorry i should stop pour saliva on the floor and close my mouth already, yes?
Me trying to find the IAC on my 2003 Toyota Matrix then realizing it's a little more complicated 😅
Best engine oil Royal Purple HPS and use there filter. Best fuel injector cleaner BG products Best Air filter and cabin air filter are made by WIX Best windshield wiper fluid Ran X 2 and 1 all season. Best wipers Trico Titan. Best rotors for cheap Power Stop. Use ceramic brake pads. Change serpentine belt at 80,000 miles to be safe. Change wiper arms every few years the springs get weak Flush all fluid at recommended times. Check ball joint and ball bearings once a year Check tire air pressure once a week Maintain the vehicle so it last a long time a lot of people don't do this.
Do all vehicles have this? Say for instance, a 1999 Chevrolet Silverado 1500
Who thinks that Chris is ready to go to A group in drifting, if you think so like comment
Really want to work on car when im older pity im only 12 i am allways messing with my moms car she allways has a minor heart attack when she sees me under the bonnet
Is this the same as the EGR on the hondas?
Man thanks your the best
Happy to help!
Thanks for making this video 👍
Happy to help!
Can I use maf cleaner
Me, an idiot, thinking this takes in consideration cars from the '70s: ._. _big bruh_
@Clash Robert i think the carburetor can break if not used for a long time or when not used good
@Mocanu Octavian43 Most probably badly tuned, I don't really know how to tune the carfil carburetor
@Clash Robert i was told the 1300 carburetor is good, if the carburetor behaves strange or badly then something is broken inside of it or its badly tuned
@Mocanu Octavian43 Yes, funnily enough, I was talking about a Dacia 1300, lol, I saw that you're Romanian :)))
Carburetor? It needs to be tuned i think
Can WD-40 clean it?
Hey Chris, Planning on cleaning my throttle body for my toyata rav4 2015, how do I relearn the throttle after I finished cleaning it? Do I need to use computer or something not too sure if it'll resets automatically once you start the car.
@ChrisFix I've seen how they disconnects the negative battery and short both positive and negative wire for couple minutes while battery is disconnected. Does that work on relearning since it resets the computer for the car?
The computer should be able to compensate after the cleaning, but I would look up and see if there is a specific relearn for your toyota!
Can I use clutch cleaner? 5:59
Brake cleaner or wash petrol can be used as well?
how fix your brain at idle 😁😁😁🤣🤣
Close your eyes and take some deep breaths!
Chris: driftstang Captions: drift sting *dumb captions*
Man im learning from you more than i have ever learned in my life ❤
Hi Chris, Please advice me what might be a problem. When i start my car AUDI A4, there's black smoke coming out the exhaust. once the idle lowers to less than 1000 RPM the smoke disappears, even when i am driving there is no smoke. it only comes out when i start the car for the first time.
Hey chris what radio do you have in your pickup?
Maan this camera angle
ITS MY BIRTHDAY
@ChrisFix Thanks!
Happy Birthday!
Love your videos pal! Can I ask, my 91 Nissan figaro has a cold idle valve, can this be cleaned like the iac?
Hey Chris is there anyway you can include classic cars on your Channel?
Bruh Question why my car is having kinda high lilttle rough idle after cleaning the throttle body
Is there any scanner u suggest to reset the throttle position? Cause its honda
You might need to let the car sit for a few minutes and let the computer "see" the cleaning and calibrate itself!
Do I have that in my e90 bmw ?
Hi Chris I am an aircraft mechanic but know nothing about cars watching your videos and having my tools and hand skills I can now service my car. Thanks a million hope we see you in tv you totally deserve it!
I'm glad you're learning how to service your car with the videos! Thanks a lot!
My car has a carburetor but the idle is so low it stalls each time I start it cold, takes about 5 tries but still runs very rough for a good while. Is there an equivalent valve I can clean seeing as I don't think my car has an idle air control valve? Carb might just need a good clean and retune.
You've been giving me slot of confidence and now more knowledge. Love your channel bro. Can't get enough
Hi Christ, is it possible to use wd40 to clean it and will it damage the iac?
“If you have a modern car like this Maserati...” let’s face it, if you have one of those you’re not watching a video about cleaning anything.
Remember to subscribe and hit that notification bell because this dude works hard
Sir can i use petrol for cleaning idle control valve?
its really help. thank you
I'm glad the video helped!
My Toyota succeed 2005 is racing when starting and only stay at one level. Help plz. We clean it but ntg
@ChrisFix It keeps on on one level and wont settle. Come up high then low then high again and stay there for some time. Someone say it is my throttle body that need to change.
@ChrisFix It just have a loud racing sound like a extreme heavy duty fan sound
Are there any codes you can scan for? It sounds more like a vacuum leak or solenoid stuck open
Low and rough idle can be caused by more then just a dirty idle air control valve, newr cars have no IAC they have throttle body actuators to control the idle speed.
My trucks idle is 500, it’s a Silverado, is that normal?
How different are older cars? I have a 1989 s10 blazer and im having trouble finding some of the parts from your videos lol. I'm teaching myself to do this kind of work.
Also check your ground wires, had the same problem with low idle would even stall at times tried everything including replacing IAC ended up just needing to clean the corrosion off of the grounds with a wire brush. Follow the black ground wire from your battery to find the ground wires. Its free to clean them so might as well give it a shot before you buy an IAC.
Best on the tube 💪🏽💪🏽 much love Chris💯💯💯
toyota is GARBAGE
Oh i think that was problem in my renault
Thx chris
Love it!! Chris you are the best mechanic teacher!!
I have a 1994 honda accord and it doesn't idle smoothly when its warm what could that be
Happy new year Chris
You’re a king 👑
Is idling at 1000 revs or a tiny bit below bad? Cause my Mazda 323 has been idling there for a few days
you are legend bro
If you have this V6 you need to change out the harmonic and flywheel and use 2001 heads and intake. 👊👊
Trick I use is the IAC from a 2004 cobra 👊 on my GT
Very good video, I loved to watch your videos...
I'am studying automechanics at Riga Technical College, and your videos are very helpful, especially in exams. Like i really enjoy these, i feel like i can disasamble, and reasamble ar car rn.😅😄
My car seems to have an air leak through the brake booster, that is out of the question, but, could that be influencing the proper functioning of the IAC valve, or of the vacuum system? In other words, I am now going to on work the IAC valve, after watching your video, but assuming that the IAC was in proper, working condition, how bad could it be the problem caused by the air leak through the brake booster? Can you give me your opinion? My car's idling is bad, no question about it.
I have ford explorer 4.6 2008. It only shakes when I stop and the gear on D. It's like gonna turn off but when I drive it's fine. Is this a symptom of bad iac valve ?
Hi Chris can you do a video on how to clean the Throttle Position Sensor and the Idle air control valve on a 4.3lt v6 Vortec engine please.
💯
The unkempt lamb systemically tickle because selection actually describe under a temporary turtle. torpid, interesting talk
My ATS is idling poorly sometimes. Need to check if it even has this piece. Thanks for the info. You can see the passion you have for your trade.
Hey Chris I have a Saab 9000 Turbo and when I redline it and let it go back to idle it almost dies I’m gonna try and find the IAC and see if that is it
Chris you are a blessing to so many, your videos are very clear and to the point. I lost my fear of some mechanic work. I found my problem and fixed it myself. I'm proud of myself.
Petition for Chris to get a Holden Commodore so he can teach me how to fix all of its problems
How is there carbon build up?
@V. Nickerson there isn’t fuel there in modern cars. That gets injected just before the cylinders
Well unless he's using water for fuel there is going to be carbon and if there is carbon there is going to be carbon build up.
Chris does it matter if i clean it with wd40!?
No. Why would it. WD is a shit lube but a great cleaner.
Would wd40 work chris? Thanks
Great video, bro I have a question??? could this idle issue can cause the car not to turn on??? I have a CR-V that after running a little while don't want to start and after trying smells gas. Please help 🆘
So good thanks for the simple explanation!!!
When he reved the driftstang it made me like and subscribe
Just when I thought I was experienced enough I learn something new from Chris every video
Chris, I do a lot of long range shooting with custom barrels on my rifles. Carbon build up is one of the things that adversely effects accuracy. So I have a lot of cleaners that sole purpose is to remove that carbon. what do you think about using something like that? I do have one in particular that foams up, and is hands down the best stuff I've used. After removing the carbon, could you use a CLP (cleaner, lubricant, protector) type of spray?
u are amazing your videos are helpful
I literally change out the IAC from my SUV a few minutes ago, and what a DIFFERENCE!!!! I have learned and save so much time and money from seeing your videos. Thank you for sharing your time and knowledge.
Hey Chris, my car was idling really high, so I cleaned it with a wd-40 throttle cleaner, now it idles to low.. what do you think is the problem?
Ansi anxious co2. $10,000 spent for full EV overhaul. Simplified.Transmission to electric motor connection mount, Cam,and crank, engine sensors wired to transmission input,and output shaft sensors.2Plus 2 Throttle position sensor to control box.Some batteries.And UGO.
He always say how much he torques bolts, from where does he take those numbers?
The ultimate ChrisFix video I'm looking forward to, Chris designing and building a car from scratch
One day!
Chris I need some help! I have taken my car with these symptoms of low idle to a few mechanics and they have told me to either clean the module or get a new one. I have got a new one filled it with premium put injector cleaner in it and bought a new mass air flow sensor to see if that would work and nothing will please help!!
hurry up and put a turbocharger on your drift stang
I am always going to ask myself who thought chis fix everything he knows ...awesome video my car has an idle issues this will help
You doing very good job 👍👍👍👍👍 Nice video 👌👌👌👌👌 You teaching very good and you very good teacher 👌👌👌👌👌🤠
