Fixed! Blown Crowns advice was right on.

We cleaned out the white dust and corrosion from the distributor cap, changed plugs, and all runs perfectly fine. However, the motor still does not stop when ignition turned off. We identified the problem to be in the alternator. It charges fine and works well in all ways. Is there another way of fixing this without changing the alternator?

My 350 mpi does the same thing on hard start, but the rpm's are ok 5000 I heard that the timing might be off. How do I check that do I adjust base or advance timing?

If it's a '02 or newer (ECM555), there is no timing adjustment. Earlier MEFI systems you jump the A and B terminals on the Data Link Connector (DLC) to put the engine in base timing mode, then you check/adjust the timing.
