anyone else got a theory
I have had a vacuum leak in the brake booster cause the same symptoms. Disconnect it, and plug the vacuum port that feeds it, and see if your problem goes away.
hey that sounded pretty good at first but.. than i thought about it.. it wouldnt make it rev so high right away when i start it..

Yes it might. Remember the ECU won't correct for a high idle right away. It takes a few seconds. Once a high idle condition is found, the ECU will try to reduce it by reducing the orifice size of the IAC valve. If the vacuum leak is too great, and the engine is getting too much air at idle from a vacuum leak, the ECU may oscillate the IAC valve trying to reach proper idle mixture. Anyway, try it. All you have to do is remove one vacuum line. It is a hell of alot easier than pulling the throttle body or IM.

This wouldn't be so frustrating if you followed the advice you're asking for.
