My bad, I adjusted the screw up although I was told not to bring the TPS voltage up past 0.6V since that will bring me into another idle fuel cell. Right now I have the voltage at 0.59 and I reset the TPS. If i raise the screw to 0.71 the car idles great but the IAC counts not much lower if any.

How big are your adjustments? If I remember right I had to go a couple of full turns on my small cam.

Ive gone a couple turns this way, a couple of turns that way!! I dont remember exactly. I just made sure that I was under 0.6V TPS. Like I said, car runs fine (atleast good enough in my mind) although the IAC valeus are throught the roof. My stits and ltits arent that far off either. Does having large IAC values affect anything if they are high? I can turn on AC in gear with no big probelms.

If you like the way it drives, there's no need to do anything. High IAC counts usually means it won't idle well, but i guess that's not true for you.
