Coffin_1997 Posted November 11, 2021 Share Posted November 11, 2021 Few days ago my truck went into reduced engine power. so far I’ve replaced the grounds, throttle body, and gas pedal assembly.. and it still goes into reduced engine power. Gives me code u0107. Happens whenever I hit a bump hard enough.. what could be the issue? Quote Link to comment Share on other sites More sharing options...

Formulabruce Posted November 11, 2021 Share Posted November 11, 2021 So, did you do the grounds on the frame extension below the drivers side door, facing the rear of the truck? If not, better get those wires and frame clean, and cover it with marine grease after. Quote Link to comment Share on other sites More sharing options...
David89GMC Posted November 12, 2021 Share Posted November 12, 2021 Cleaning the connectors to the throttle body worked for me. Quote Link to comment Share on other sites More sharing options...
