Sounds like a control pressure regulator.  Check the fuel pressure when it
is trying to warm up and compare it to the specs.  See the Bentleys manual

Fix the burned out license plate lamps.  It can also be the glove box lamp
I've heard.

Could be the control pressure regulator also.  It could also be an improper
mixture adjustment..

This does not sound too good.  It should be fixed the right way if there is
a problem.

Probably.  It can also be cracked wires in the door jamb.  It is common to
have cracked and shorted wires in the rubber boot in the door jamb.  This
usually means cutting and splicing in new wire piece by piece.
