Engine Performance problem
1993 Chevy Corsica 6 cyl Front Wheel Drive Automatic 140000 miles
I noticed a couple days ago my car was idling rough, even when driving downt he road, you could feel the rpm's jumping up and down driving at 35 mph, 55, did not matter. No codes have been set off, ran Genesis Diag today, and doing tests, looking at all the readings, they just keep climbing and climbing, reset, and do it again, It shows rpm's climbing, Temp at start up climbing, volts to TPS, all of them just keep climbing, and reseting and doing it again. Is my PCM fired?
have the same problem?
