I've had issues with the wax in the fitv backing out some. Easy fix and one more thing to check off the list of possibilities.

Any more info on the chat kind of car?

If it's obd1 it could be the fast idle valve.
Start ot up and let it idle.
Cover the bottom hole in the throttle body with you finger, if it stops that you need to clean or replace the fast idle.
If it doesn't stop then cover the top hole and see if the motors dies.

If it doesn't die then you got a vac leak.
