 the guy who works on our car and he said do not freak out -- it is not a big
 deal, probably a electrical problem. Any ideas??? Althea-91 GL

Yeah, I've had this problem - damn near drove me nuts until I figured out that
the oil pressure was O.K.
It would come on with the buzzer whenever I hit a bump or crossed rough
railroad tracks etc. with the engine rpm above 2000.
I learned that when it was raining it was more prone to malfunction than when
it was dry.
Very recently, while replacing a water pump, I took a long, hard look at the
sensor(s) and wiring. What I found was a plastic snap-on cover over the
connector on the sensor down below and to the left of the crank pulley.
This cover had it's open end up so if water ever got into it, it would tend to
stay there.
After determining that there was no immediate danger of anything shorting this
connector with the cover off, I removed it. It snaps right off of the
connector fairly easily.
Haven't had any sporadic blinking oil pressure light or pesky buzzer since and
I have recently driven through monsoonish rains.

Hope this helps.
