I posted this in the electronics forum and didn't get a response. Im hoping someone here can help.
I have an 80 Malibu with a 383 stroker. The problem I am having is, when you turn off the key, the engine shuts off for a split second, then starts back up and runs for another 2-3 seconds. I originally told my mechanic about this, and he seemed to think that there may be something wrong with the ignition box. All of the wiring to the ignition box (original car wiring) is original. The car ran about 2 years ago (with a different motor, same ignition) and never had a problem. The engine is not running hot when it happens, somewhere between 180-200 (reading from the intake). Never does it while the engine is cold.
Cam is a Lunati Voodoo Duration 268/276, Lift .489/.504. Ignition is an MSD 6A (4-5 years old). Distributor is an MSD Pro-Billet Vacuum Advance. Timing is set somewhere between 32-36 degrees (wasn't there when the mechanic put it in time). Accel 7.5mm wires. AC Delco plugs.
I am at a loss. Anyone have a suggestion? Don't really want to shell out $200+ for a new ignition box if that's not the problem. May have given more information than needed, just trying to cover everything I know of.
Thanks for the help.
