AIR AND FUEL SYSTEMS - CHECK





When diagnosing a low power problem, first troubleshoot the air and fuel systems to make sure the engine is receiving adequate intake air and fuel.





Check the intake air system for leaks. Make sure a sealant is used on the through-hole capscrews which secure manifold cover to the head.

Verify the turbocharger is operating correctly.





Check the fuel system for correct timing and fuel delivery.
