    Post Terminator X Cylinders #4, #7, #8 Dead

    Just installed the Terminator X and have been driving it for about a week getting the tune dialed in. Was out in the car today and it was running fine. I shut the car off and when I fired it back up, it now has a misfire. Coils for cylinders #4, #7, #8 aren't firing. I checked my coil grounds and both of them are tight. I didn't change anything in the tune and not sure where or what I should check next. Thanks for any help.

    It's really strange that you would have three coils go out at the same time. Have you verified you have power to the coils? Are you getting control from the ECU to fire the coils?

    What are the LEDs telling you? Andrew
