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!

Just curious if a dirty IAC valve would also cause a rough cold start
Hey Chris, I don’t know if you’ll see this but I have a 2009 saturn sky redline and I just recently did a head gasket change and I put everything back and made sure everything was correct but now when I start the car it runs rough on idle. When I bring it up to 1700 to 2000 rpm’s, it runs good but it’s whenever it’s idling it seems like it has a bigger cam and has a shake and seems like it’s going to stall. Can you try and help me? I’ve tried Ai, Forums, the internet, and I’ve found nothing that helps.
Is AAC valve the same as IAC
Does it still apply if my idle goes under 500 only after a long ride?
i did everything else and my 3.0 runs like a champ…….until i come to a red light and it misses and vibrates…….poor old 2002 Taurus with the original Valve thats never been cleaned,,,,, i went ahead and bought a new unit and will put it on tomorrow…..hopefully that does it….if not ill have to do a smoke test.
