Re-Location of PCM
Thanks Johnny MC, Now that I know where to find the PCM it will help. One thing I did not mention was that I had disconnected the IAC and the fast idle disappeared. Also when I measured the voltage at the connector it was about a volt low. Just for giggles I will reconnect the IAC tomorrow and see what happens. How does the MAP sensor or the TPS fit in. Thanks for the help. I'll beat this problem yet.

What are you trying to figure out
Voltage at the throttle bypass valve will read different
volts at different temps.It will be determined by the MAT
sensor and the ECT sensor, manifold air temp and engine
coolant temp.The TPS just sends different volt signals to adjust
the air fuel at different throttle positions.MAP sensor tells the
ECM at what altitude the car is running in so it can adjust accordingly.
