Got the 96 Buick P/A, 3.8L engine. The oil pressure light comes on at startup when cold and stays on for about half mile. After 10 minutes it comes on again an d sometimes flickers on and off. Sometimes goes off when revved but coasting stays on alot. You can only rev it so much when driving in the city! Is it a sensor, the filter or wiring? Give specific direction on the location of the sensor as I don't work on this car very often. Just finished a 4 hr. serpentine belt job

Anytime an oil pressure light or gage indicates a problem, the first course of action is to install a mechanical pressure gage in place of the sending unit (or sensor) near the oil filter and see what it says.

Oil Pressure or Oil Level?

My daughter's Cavalier has an Oil Level light that comes on if the oil level in the oil pan is over a quart low, it stays on for only a few minutes then goes off as oil starts returning to the pan. I would be extremely concerned anytime an Oil Pressure light came on. I would park the car until the problem was resolved.
