I have a 97 Cherokee Sport. It has recently started cutting out when driving. It bucks and seems like it is possibly missing. I have replaced in the last 4 months, CPS, MAP, TPS, plugs and wires and O2 sensor. I had an issue like this before but not as bad. It would stop when the O2 sensor was unhooked. I resolved that issue and it has been fine for over a month. When driving it the jeep will cut out like its missing sometimes doing it 4 or 5 times in a row. I have checked for vac leaks also. I have recently changed the valve cover gasket but can't remember if this started before or after that.
I had it checked for codes and nothing is showing up.

Any ideas?

 

Just from past reading have you checked your battery cables and clean your grounds?

 

Clean your IAC and Check your O2 sensor fuse. Just fixed the same issue and it was just a fuse. Also clean the throttle body with some carb spray or seafoam.

 

Battery cables are all good. I have cleaned the IAC. I had a similar issue to this a month or so ago and was told to check the fuse, there was actually no fuse in there so I put one in and it was running better for awhile.
A few weeks ago whenever this started it also would randomly have a high idle after driving it. It only did this a few times though.

 

High idle tells me you need to clean throttle body also. I would start there. Also, which O2 sensor was replaced? Being a 97, there should be an upstream and downstream sensor.

 

The throttle body was cleaned approximately 4 months ago. I replaced the one closest too the engine. Not sure what that one is called.

 

The O2 sensor closest to the engine would be the upstream O2. When you replace O2 sensors, it's best to replace both at the same time.

 

So after looking over the jeep I decided once again to clean the throttle body and sensors. I did a deep cleaning on it and put it back on. The problem was fixed! It has been over a week and it still is not cutting out. Not sure if it was the throttle body or one of the sensors but easy fix so far! Thanks everyone for the help.
