Sounds like you may have a sticking throttle. I would remove the cables from the throttle body and determine if it is a problem in the cable or in the throttle shaft/plate itself. I'm betting that the shaft/plate is the problem. If that is what you find, then I would recommend that you remove the TB and thoroughly clean it with some sensor safe carb cleaner. Remove the IAC (idle air control) valve and clean the bore that it goes into as well as the pintle on the end of the valve, being careful not to move the location of the valve.

Good luck!

You might also check for a vacuum leak. If you have a vacuum leak, it can make the vehicle idle faster.
