  1. Hello

    How did you adjusted your timing? Start with make sure you set the timing right with a timing light.

    Remember that you have to:

    ground the “A” and “B” terminals on the ALDL connector under the dash before adjusting the timing

    and drive it hot and set to 8 degrees

    Check for fault codes/blink codes in the ecu if you can see any information. 🙂
