    I already addressed this in post #2.

    2. When I quickly hit the throttle, it takes time to return to idle.

    Thanks, but all the wiring etc., is brand new. It has a Painless Wiring kit installed and a 1-wire alternator. The reference you sent me does not relate to my application. I will reread the IAC Notes, but I think I have all that OK.

    Then I wouldn't know why it runs-on.

    Evidently not. Check your IAC Ramp Down Parameters.
    Scroll down to "Typical IAC Control/Ramp Down parameter settings."
    This is all in the 3.5" LCD Touchscreen instruction manual (LINK).

    Engine run-on was caused by the cooling fan wanting to pull voltage, which caused the MSD RTR distributor to keep firing. You learn something new everyday.

    Hey Danny, should I look at running a 6AL on my setup for ECU controlled timing?
