Oil pressure issues

[Teresa Maxwell]

I have a 99 jeep Cherokee the oil pressure gauge keeps going up and down and will stay down for a while then gauge goes up the oil pump was replaced and the sensor was replaced. I really am puzzled could someone help me ?

Welcome to the forum. I would recommend verifying your oil pressure, using an alternate gauge, since stock gauges are inherently inaccurate.
