Engine Performance problem
1991 Chevy Silverado V8 Four Wheel Drive Automatic 237890 miles
I recently purchased a 1991 Chevrolet Silverado Z71. I've had it tuned up and have fixed all the leaks. I have had trouble with rough idling and lately the "Check Engine Soon" light comes on when driving at expressway speeds. I will stop the vehicle at the side of the road and let it sit for a few minutes. When I start it again the light is off. This is happening everyday now on the way to and from school. I have put some additives in the gas tank to get rid of a moisture problem in the gas tank. I was wondering if the fuel filter might be getting plugged up. Also there were some cracks in the crossover pipe which I have repaired.
have the same problem?
