Question about 1994 Jeep Grand Cherokee
Plus low oil pressure
Yeah either one...but that doesn't cause the low oil pressure light to come on. When you have oil pressure light comes on, that means that your oil pump is failing and/or your main bearing seals are failing. Costly repair.

Idle at 40 is fine. Do what I said and give it a chance to work...chances that an adjusting nut has loosened up is ) if it's a 4.0 (you didn't say) these have non adjustable valves. Any engine with adjustable valves uses "interference thread" nuts that do not back off.

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?
