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 the
manifold cover to the head.
Verify the turbocharger is operating correctly.
Refer to Section 3 for additional air system checks.
Check the fuel system for correct timing and fuel delivery.
Refer to Section 5 for fuel system malfunction diagnosis.
