Jeep xj knocking when accelerating and loosing power

My 1996 Jeep XJ 4.0 has been having a few problems. For starters its idling week and starts too back up with fuel until i rev it a bit. also when accselerating it will make a knocking sound and then loose power until i lift off the gas and press again and it catches itself and seems to fix the problem. Ive also lost first gear recently and im hoping this is due to a failed solenoid. Ive pulled the codes ik i have an o2 sensor on the fritz but thats the only thing it told me was wrong. im 17 and new to all of this any advice would be amazing.

Re: Jeep xj knocking when accelerating and loosing power

I'd start with the O2 sensor code and go from there. The knocking would worry me...oil pressure and oil good?

The oil is good level wise. but my oil pressure has always been noticeably high. Usually 3/4 of the way on the gauge

My knock turned out to be my flex plate, make sure those bolts are tight
