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!

  • 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?

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.

  • 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.

    Linbert Dempsey RefuerzoLinbert Dempsey RefuerzoPrieš 8 dienų
    • @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?

      Linbert Dempsey RefuerzoLinbert Dempsey RefuerzoPrieš 7 dienų
    • 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!

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.

  • 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.

  • 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.

  • 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.

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?
