The ECU is configured in a bank Fueling scenario.. The Bank that had the 'Proper' Injectors would be running normal fueling. The 'Other Bank' would be a Skiew.. the Two Cylinders that are 500 injectors will be running RICH, and the ONE Cylinder will be running LEAN.. Idle would be Krappy, The ECU can not fix only one cylinder for fueling.. ALL the injectors need to be the same.. Is there a back story to this.. ? Cj
