Update on the PCM problem:
Installed the 'repaired' PCM. However, I will be sending it back to the repair tech
because pin 71 of the PCM is shorted to ground and all that happens is fuse 20 blows when power is applied. The circuit (361) is 2M ohms until C103 is connected to the PCM, then it reads 7 ohms. I'll keep you updated....
