If you move the plunger around when cleaning, when you first start the car up the rpms will likely race until the plunger gets adjusted properly.
I'd start there and see what happens.

OK, that makes sense. I have been too busy this week to get to it, but I will definitely take it off an clean it this weekend. Thanks for the explanation.
The motor is a stepper motor, and there may be a spot where carbon has built up, and that is the spot the ECU adjusts the IAC valve to when the AC is on.

Twolf...Okay, just wanted to make sure, sorry it was off topic
It was a legitimate question, because I wondered too. Wouldn't be te first time someone drained the pan, read the manual and put 9+ quarts in to replace the 3-4 quarts that came out.
