yep it threw an SES light and I had it tuned.

You could also test the IAC with a multi meter... If my memory serves correct it has to be inbetween 0.05 to 0.07 and I think 0.05 WOT.... Oh and you dont need to have the car running but do have the key in the on position.

If you still have problems let me know and I could direct you to a friend of mine.
