2010 Chevrolet Silverado 1500 LT 4.8L MIL Lamp on
Posted to GM Driveability on 11/20/2021 30 Replies

Very frustrating....the trims only do this at an idle or a cruise at speed. as soon as the gas pedal is touche they drop from 30% down to 0, when I reset the alcohol I also reset the fuel trims, when I changed the MAF I reset the trims again no change they...
