Thanks, What I really needed was the location for the IAC. However, this truck is apparantly a self-healer. I started it up yesterday morning with an outside temp. of about 35 degrees, and the sucker did like it was designed to do. The check engine lite was still on, but yesterday afternoon when I left work and started it up, the light was gone, and the idle was fine. Must have had some carbon build up that passed thru. But next time I will at least know where it is located.
