O2 Sensor? 1989 C2500 5.7
Hi All, My 89 C2500 is running silly rich. It smells bad and I get buildup on the plugs somewhat regularly fouling one.. My first guess is the ECU is in some kind of a limp mode as the PO apparently eliminated the O2 sensor. At least I think this truck had an O2 sensor, I am not entirely...- Triplesn8s
