My 1999 Jeep Grand Cherokee Ltd. Starts up fine cold. Just a turn of the switch. However, after it warms up on the road, the oil pressure gauge starts to bottom out. I will let up on the gas and accellerate again and the gauge will rock back and forth from zero to where it should be. What is wrong with it?

You always want to try a new oil pressure sender first just to make sure the gauge is accurate but judging by the mileage it's probably just worn out and has low oil pressure. You could put a new oil pump in it but I don't recommend that with that high of mileage
