I'm guessing you mean idle? Possibly your throttle position sensor. I have had the same issue before.

unmetered air such as a vacuum leak. IAC unplugged?

Yea sorry for the spelling but sprayed brake cleaner on the engine never idled down or up so no leak iac is plugged in but havent swapped out the tps but will do next

what about the timing? I know that a lot of timing will change the idle of a car. And just because the IAC valve is plugged in and reported numbers doesn't mean it is working.

Scan tool. Then come back and report what you find instead of guessing.

Throttle position screw accidentally turned maybe?

Doest have to throw a code. Hook up a scanner and watch the fuel trims as you spray. The bottom of my intake was cracked and idled high. When you sprayed brake/carb cleaner the idle didnt really change but the trims sure did go nuts.

Make sure the throttle cable isnt too tight. Happened to me before.

this might be a stupid question how do you adjust it cause my gas pedal is sticking so that might be it

If you have the idle screw too far out trying to get it to idle lower it will stick. Dont forget to reset your IAC. Have you done that yet?

try checking to make sure the intake is torqued down properly. I'm having the same issue on my car, and I'm going to try that this weekend.

what part of town do you live in? maybe need another set of eyes to look at the problem.

well, if you would get your foot off the damn gas pedal it will stop revving..... no but seriously its probably the throttle position sensor
