Well it's random. At start up I look at the scanmaster and see anything from 45 to 130...and in short time it goes up to 175. Won't idle and if it does, it hangs around 450-500RPM, choking. I don't think resetting the IAC does anything.
I grounded the ALDL and checked the 4 prongs with a test light and found all four to have power, which according to Mitchell, means there is a faulty IAC connection or IAC valve. 3 valves later, same thing so now I am thinking the wiring is screwed up somehow. Changed the ECM also and different chips. No difference.
