remove the IAC and clean it good with some carb cleaner and reinstall it.

is the pedal getting stuck on the floor mats? that is what happened to my buddys maro last summer.

if your idle screw is set to low the gas will get stuck at idle

carbon buildup in your throttle body is causing that, either that or your cable is binding

you could put a throttle return spring on the tb to help

me alot fast than u

lucky that you could.. but the t/b needs cleaned about once a year..alot of times it will make it idle better

If you put a return spring like in the "carburated" days of old. Would this work on a fuel injected system? Would that rapid return of a spring, when you let go of throttle harm the engine??????

I don't understand why you would think the IAC would cause the throttle to stick. A "hanging" idle, where it comes down slow - yea that would make sense - but not physically causing the pedal to bind
