Question about 2004 Chevrolet Cavalier
I was told to check the fuel pressure regulator.Is it possible fuel is bypassing the regulator and putting fuel into the intake making it run rough at idle?The car runs good at higher rpm.Thanks.
A car that idles rough and clears up is the sure sign of an o2 sensor shorted this may not give a code if the short in the sensor is bad the computer will eliminate its input to protect itself
