Hello. The engine computer will need to be re adapted or re learned to the new throttle body. This will require a high end computer scan tool or a GM tech 2 scanner. A technician, like one from YourMechanic, can inspect for trouble codes and synchronize your vehicle’s throttle body and engine computer in the process.
