Default 89 idled at 2k after I brought it to a stop

My 89 has been gone over - it has only 12k original miles on it.

Today I was pulling in to work, and I coasted into the parking spot, then pulled the E-break..

I heard a revving noise - my car was idling at 2k. I shut off, then off, and it was fine..

Any ideas?

If the throttle was sticking, wouldn't it stick after I shut it off/on?

Check the engine codes. Sounds like something is telling the IAC valve to go wide open.
