WhoopsThat’s the passenger side what does the driver side look like. Wish I had some advice, I have a persistent P0353 code that Iam chasing down.

I battled an intermittent misfire problem on my 97 with 151k miles for 2 years replacing everything dist cap, wires, etc.125K
I've got all the tools I need to do the timing chain as I've done it before in my old XJ ten+ years ago. Like hell I want to do it. Jez, I hope it's not the timing chain. I can't even test this theory without removing the front end to take a look.I battled an intermittent misfire problem on my 97 with 151k miles for 2 years replacing everything dist cap, wires, etc.
Finally checked timing chain slack at 175k which showed 8 degrees slack.
Replaced timing gears and chain and all misfires gone, period.

It is a bit of work but if that timing chain has too much slack it's gotta be replaced. Yes they are sposed to last the life of the motor but they do stretch from wear. To me that chain has too much slack. I would replace it. Nice video.I've got all the tools I need to do the timing chain as I've done it before in my old XJ ten+ years ago. Like hell I want to do it.

Lol I did. Over ten years ago. On the XJ. I've never opened up the TJ.It is a bit of work but if that timing chain has too much slack it's gotta be replaced.

IIRC he has distributorless ignition.Have you replaced the cap and rotor
Is that oil of fuel at the top of the plug?Double platinum. Though the gap in the trouble code cylinder #1 has widened to .50. #5 was .25. It's as if I never set them in the first place. Lol I'm going to test the coil pack as soon as my wife gets home and can crank the engine for me while I watch.

Normal gunk. Had a leaking valve cover a while back.Is that oil of fuel at the top of the plug?
Did not know that. I'll double check my grounds.All 4 of those codes are related to lower than expected voltage. If you are confident that the battery is good, I would check and clean all grounds related to the PCM.
So I've heard. I can't recall what brand I have. Could also be the fuel/air ratio is off (not yet learned) and the O2 sensors are in code because they don't know what temp to be based on those mixtures. If that's the case (and if I'm not talking out my backside with that logic) it should re-learn on their own.Sounds like progress (I hope!).
You didn't say what brand O2 sensors you're running, but our TJs are known to be very picky about it. Check out this thread for the reason why and links to the ones you should be running..
