There is a ground that connects the boddy to the engine on the driver's
side of the vehicle. Clearn the contacts for that ground. Even consider
replacing the wire and connectors, and possible adding and additional
ground. Though I have not had the actual experience myself, according to
my reading of posts from the list over time, this gound has often been
implicated in problems such as the ones you are experiencing.
