02/11/2022Q: What should I pay attention to about the Intake Air Plenum Gasket?
A:
Always begin your diagnosis with the Diagnostic System Check-Engine Controls for any MIL or driveability concerns. The Diagnostic System Check directs you to the next logical step in your diagnosis. Follow the instructions in this bulletin should the rough idle, misfire, or DTC P0300 diagnostic procedure point to an air leak in the intake manifold gasket. Following the published diagnostic procedures will improve diagnostic accuracy and support our fix it right the first time approach.
