Hi,
Just wondering if any of you use an idle stop solenoid to help with engine run-on (aka dieseling) when you turn off your engine?

Occasionally, I have engine run-on when I turn off the key in Park. I've already lowered the idle speed as low as possible, so don't think there's any more I can do there. I know that I can turn off the engine in gear, but would like to be able to turn off the engine in Park.

Attached is a pic of one option: the Holley idle stop solenoid (P/N 46-74) and the bracket (P/N 20-9). According to Holley, this bracket is designed for 4150/4160 baseplates.

Any comments or suggestions are welcome.

Thanks
