My '84 4000S Does this too...

At seemingly random times the oil pressure light (and the annoying buzzer
which would be nice if it worked) comes on for 2-3 seconds.  This maybe
happens once a week.  I had the sensor replaced to no avail.  My ignorance
lies here...  Would this sort of thing be a grounding problem in the wiring,
a chip problem, what?  BTW, the oil pressure IS fine at this time, the
gauage shows no problems at all, and I had that cross-checked with a known
accurate guage...

Tanx.
