1995 Oldsmobile Aurora review from North America

The first things that went wrong with it are the Oxygen sensors, Throttle Position Sensor when I first got the car. After a 1000 mile trip it started to miss and lack acceleration, so I put the tester on it. The readings made no sence so I called the dealer. It acted like it missing. It said I was running, temp wise, at 115 f. I knew it was not and it seemed to be quite hot, the fans would not come on. The dealer said it was most likely the Power Train control module. I have a spare PCM rebuilt that came with the car, but it needs to calibrated to the car. Does anyone know how to do this or is this something I should let the dealer do? The car is at the dealer today being checked.

The information I've gathered so far from this posting area is that the Control Module is an issue with this car, Should I be looking for a root cause for the failure of the Control Module like the alternator or is it just the Control Module decides to go it just goes? I really like the ride, drive, power and comfort of the car. If this is a way of life for this particular model I would appreciate some input. I only paid $3900 for it. It has an engine with 48K on it and a transmission that was replaced at 60k by the dealer. The interior is almost spotless. So if this fixes it I would like to keep it, but if this is just the start of the issues?!
