    When Car idle and not in gear it will continue to rev between 2k-3k rpms

    I own a 2002 wrx and I've noticed that when either car is not moving or is it will rev within 2k and 3k rpms when not in gear. No mods and has 130k miles. If I rev the car myself to about 4k rpms about 2 or 3 times the problem goes away temporarly. No the floor mats are not the problem nor is my foot accidently touching the gas.

    1. Check the tightness of the two throttle cables at the throttle body
    2. Clean your IACV
    3. If all that doesn't work, does it work better with the MAF unplugged? Should idle around 1500 with it unplugged, around 750 normally.

    I'll check that out but the exact problem is that it revs up to about 2k-3k goes back down to 1k or less and then continues to repeat

    I'm thinking that means either your IACV is sticking fairly badly, or you're running crazy lean for some reason. Let us know how the steps about go.
