Important:
*

Failure to correctly identify the cylinder positions may result in the replacement of the wrong injector.

*

During replacement of the injectors, inspect the inlet and outlet fittings for corrosion or contamination.

If the engine did not have low compression on any of the cylinders, replace the fuel injectors on the cylinders that had low cylinder power
contribution, high balance rates, or a noise/smoke change during cancellation.

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.  See: Computers and Control Systems/Testing and
