ABS and Trac lights stay on. Check engine soon goes on most of the time when shifting at lower speeds and stays on but doesn’t seem to affect cars performance. I’ve had it checked numerous times but they tell me it’s something in the computer system but know what exactly it is.

Have the car scanned for those codes, too, and post them so we can try and help you.

I have the factory service manual for that if you ever get the codes. Our 95 Aurora used the same book. The thing with the 95’s though is that they were between OBD1 and 2, and places like AZ can’t read them. So you really need to have the dealer or folks with more sophisticated scanners read the code.
