stop that! you are doing a great job. for future ref, as im sure you figured, IAC and IAB are used almost interchangably (C= control; B=bypass). just in case you run into one or the other.

good luck.

OK I just pulled the IAB and it was baaaaad. The rod that goes throught the center of the IAB was coated in chunky black carbon, I mean CHUNKY. It took an entire can of carb clean to get it off. Im letting everything dry before I put it back together so I'll let you know if it made a differance later. Damn I didnt think an intake part could get that dirty...geeez. Just curious, was it necessary to remove the electrical connection on the end of the sililinoid before cleaning?

Why is it always the last thing you try???? Took her out for a run and its almost back to normal. Searchs just a tad but it drops down to normal idle almost immidiately and its a lot smoother now. Gonna go over everything one more time and reset the TPS and idle and we should be good. Thanks for everyones help!

yep, that is how it goes.

not sure what you mean about the connector??

if you reset the KAM, it might learn a little quicker (might help with the hunting you are seeing right now).

good luck.

The adaptive strategies of the computer are pretty amazing. Mine had a spat of wanting to idle down a couple of months ago. Did it a few times on a cold start - would act like it wanted to die and then the iab would catch it and speed it back up. It'd do that a time or two over 15 seconds or so, and then idle fine. Well, when it would try to die, I'd step on the gas. What I finally tried was, NOT stepping on the gas. I figured that after a while of the computer having to 'catch' it, it would learn. Sure enough, about 4 starts later, it was back to cranking right up and settling right into the idle. No drop, and no having to 'catch' it. Once the computer saw what it was doing at start up, it learned, and made adjustments.

JT's suggesting you disconnect the battery overnight to clear the keep alive memory out of the computer so it doesn't remember all the funky stuff it was trying to do when it was running crappy. If the parts are working correctly, it may 'learn' more quickly without the old memory.
