Loss of Power and High Oil pressure

I have a 2000 TJ with 150k miles. Yesterday I noticed a good bit of loss of power and the oil pressure was pegged out at 80. After i pulled off the interstate it went back to 42 ish under load and around 18 at idle.

The guy at NAPA was trying to tell me it was the oil pump, but I did not understand it loosing power?

Is that normal for it to act with an overactive oil pump or is it the sending unit or something else.

High Oil Pressure

hey, sorry not much help but I am also having similar issues on my 02 TJ 4.0, and I only have 65k. I'm going to post under a more general thread and see if we get some answers...

Not sure about loss of power ... did you get any codes?

Oil pressure could be your oil pressure sending unit going bad.
