Engine Performance problem
2000 Chevy Silverado V8 Four Wheel Drive Automatic 135000 miles
My Silverado is bucking when I slightly hold the gas around 55 mph. I recently had the fuel pump and filter changed. It is throwing code po449 (evaporative emission control vent/solenoid control circuit malfunction). If this is causing the bucking, how do I fix it?
have the same problem?
