2008 Chevrolet Silverado 1500 LS 4.8L Poor Idle Quality, Hesitation, Surge, MIL Lamp on
To all you gm techs out there, i could use a guiding hand on this one. Vehicle came in with dtc p2138 stored and a message stating reduced engine power. I found 1 tsb regarding this dtc and inspected the ip connector to the body harness but all checked out ok....
