Is their anyone out there that repairs or exchanges 92 - 93 automatic PCMs?
Mine is acting up. No grid heater preheat, only starts working after the engine starts.
Also the the alternator over volts after start up for a few seconds, then the wait to start light blinks on, the voltage goes to normal and the grid heaters start cycling down normally. Why the alternator is over volting is strange, it is on an external regulator.
