Got the IAC in today...
To quote homer, Sweet Merciful Crap! After months of hunting down my idling problems, and replacing things piece by piece (everything helped alittle). I ended up with a consistent idle surge from 600-900 RPMs when the car was warmed up. It was suggested that the IAC should be cleaned or replaced. Once I got it off and saw what it looked like I decided to replace it. Bought a new one, set the proper pintel length, reset it according to the manual, then I just listened to my baby purr... idle stays almost dead on 600 RPMs... 
next week I'm gonna replace the starter, and clean up some other items... then, FINALLY, let the modding begin

Awesome... Makes me think about changing mine for good measure. What's the part cost, and how did you go about setting the pintel length? I have the service manual, but looking at it yesterday, I thought it was a little vague on that particular process. Thanks...

That's the IAC i got... you can see its' 27.99. and it's a wells model not ACDelco. The ACDelco one was 29.99, but the autozone I went to did not have the delco in stock, only the wells one. I wanted to finish the project, so I got the wells.
