The IAC is what seems to be the problem on start up and it also acts as the acceleration modifier thoghout the whole rpm range. The car runs good after it starts and it only has the problem on the top end.

I am going out today to get some datalogs done to review what is happening now that I have fresh parts to eliminate any questions as to their input to the problem.

Thanks for reminding me because it can be something simple when you are doing it for the 1st time, unfortunately I have been thru the school of hard knocks with this system and it seem more like a fire drill than an emergency.

Just an FYI for everyone, although you could say the IAC calibration can effect tip in therefore acceleration, in reality the IAC and acceleration modifier are not directly related in any way on any system, Accel or not. 2 different things.
