Tip of the Month: 

When replacing the Injectors, you must change the Injector Trim Code for proper engine operation.  (Tech Tool Operation # 2371-07-03-01).  The Engine Control Module (ECM) will compensate a small amount for each injector in order to provide smooth idle and functioning. When replacing the injectors this compensation must be reset.
Perform the “Reset Injector Compensation Values” found in the Cylinder Balancing operation.  (Tech Tool Operation # 2387-08-03-01).

Note:  The reset function will be added to the  Injector Trim code operation in a future Tech Tool update release.
