what a disaster. service engine lite on and purchased a new Aftermarket MAF Sensor. Still showing code. gave up and installed NEW GM part 550.00 and still throws P0101 code.
has anyone ever had this problem.. truck runs great, not missing, no smoke.. at wits end.
we did change water pump and coolant bypass tube. the bypass tube had a washer welding inside that seemed to restrict flow.(what the hell)
Can these be related? Looking for any help I can get.. THANKS
