Thread: Injector Question

  1. #1

    Default Injector Question

    In the process of trying to figure out a misfire issue with an LS1 build. I found that cylinders 1, 3, 6 & 8 injectors are pulsing once and the rest are pulsing twice. I'm completely ignorant with EFI. Does anyone have any idea what I might have done wrong? I'll add any more information needed. Thank you in advance.

    I would start by recording a System Log of the crank & cam signals, and check your Ignition Parameters too (System ICF). (Datalog & System Log Information)

    Danny, you were correct! I had a bad cam sensor.
