It could be oil pressure is low, in which case shut off engine and haul to shop. Or it could be a false indicator, i.e. faulty oil pressure sense circuit (sending unit/cable/connect).

SOURCE: 95 GMC Jimmy 4.3l W vin rough idle

My problem was solved when I repaired my 4 wd activation dash switch. The switch was contacting on 2WD & 4HI at the same time. The front differential activation is vacuum activated possibly creating a tug of war that didn't actually engage it but drained off vacuum from the engine? A theory at best but stumbbled across it because I knew the switch wasn't working properly I repaired it and low and behold rough idle disappeared and all is good for 3 weeks running.

SOURCE: 2004 Grand Cherokee: oil pressure fluctuates

if you know for certain that the sending unit is correct and the guage is accurate, then yiu may have big problems.....while the engine is running open the oil filler hole.. is everything wet with oil? or does it look dry or just a little lubed? you can allways install an aftermarket oil pressure guage(crappy tire) if you get the same results with that then you may have a week oil pump....worst case scenerio... need an engine rebuild as the moter may have wear issues.does the pressure slowly drop as the motor warms up? at idle ? does it jump up when you step on the gas?

Exhaust pressure sensor a possibility if it has a DPF (diesel particulate filter). Has it had its fuel pump recall, the oil pressure light could be just the constant cranking and running the battery low.
