420 SEL engine won't stop

Hi, happy to be a part of this shindig.

When I turn off the key on my 1990 420 SEL, the electronic stuff shuts down (windows, radio, etc no longer work) but the engine continues to run. I can turn it off, remove the key, and walk away, and it will run until it runs out of gas. I can also disconnect the battery under these circumstances, and the car continues to run.
Any thoughts on what the problem might be?

You will need to find a young Priest and an old Priest.

Ask the guys who will know the answer, I doubt if the priest can do much unless he is a mechanic
