It could be your IAC that is causing your idle to be so high.

See if cleaning it helps

Something I've run into in the past is the throttle cable getting pinched causing the throttle to not quite release. Check for fluid operation of the cable within the sheath.

Second, make sure your throttle return springs are intact and not hitting against anything.

Third, take a can of carb & choke cleaner and thoroughly clean around the throttle plates, as well as every port in the TB. Make sure you have no green or white crud building up in the IAC or TPS connectors (or anywhere else for that matter).

We're seeing this through your eyes, and you haven't given us a whole lot to go on. I hope this gives you a place to start.

It could be the fast idle valve. Bad map/ tps/ iacv/ coolant temp sensor
