- So, despite weeks of research and part hunting, I finally found all 4 new oxygen sensors for my jeep. It has been advised that many after market sensors provide poor readings or longevity with Wranglers, having different start up times etc. NPK parts ate recommended, and due to the numerous models and variants of wranglers and even there sensors, I was satisfied to find them. Sadly, as Jeeps are, unexpected issues arose during install. despite the correct parts, my plugs seemed older, from pre 2000 models. this is a problem I've found often in my 2001. it appears to be a mix or hybrid of older and newer parts, and make more complicated that this was a Mexican produced variant and now an Australian import right hand drive! needless to say, many of the plugs were offset enough to warrant modification or rewire. But all were successfully installed in the end.
I recommend a cold engine despite all the advice on heating (heat causes expansion of metals and I need not explain that further, lol). heat impeded removal for me at least. I recommend an appropriate o2 sensor tool as it makes life that much easy given this task. WD40 was used to help loosed one sensor that had rust fused. all others were quite easy to remove. This video documents the 20 or so minutes of work it should take providing you don't encounter severely siezed bolts or have to rewire everything like I did.
hope this vid helps anyone who encounters similar issues.
happy cruising ;)

Thanks man this is great guidance for my weekend project
Good work mate! But, how did you unplug the O2 2/2 sensor plug? I haven’t been able due the narow space where it is located the connector.
I really like your starter button. I had a 93 that I had to put one on
Do you have a link or information to that socket you used?
It's just and 02 censor socket. You can get one at any hardware/AutoZone like store
Good vid. But why the annoying music?
Don't use flammable stuff on exhaust. Water with a little dish soap is a better idea here and then anti-seize when you put them back in.
My battery PCM and Fuse/Relay Box are on the other side. So much easier to get in there.
