Dieseling with the igntion turned off is usually caused by red hot carbon deposits in the combustion chamber.
Try something lke Lucas upper cylinder lube with Injector cleaner
to get rid of the carbon deposits.

Heh, yes if you have your idle speed set to high then the butterfly won't close enough and when you turn off the car the engine will continue to putt.. Trust me I had that shit BAD the one day when I screwed with it.. i had a damn idle of like 3000rpm lol.. turned the car off at a mini-mart and the thing stayed slamming the pistons n valves around for like 30s... But he says he didn't screw with anything and if your idle is still the same.. I bet it's your timing.
