Since I got my Jeep the ignition has been quite temperamental, generally it needed a very slow turn of the key to make it start, if turned quickly you’d get no crank at all, however apart from that it had no issues starting at all. I got in this morning and it failed to start, however after...

Hello all, I have had issues with my TJ since I got it, it seems to be intermittent. To summarise its poor on fuel (very poor I get about 120 miles out a tank, it stalls, misfires, has surging issues and hesitates occasionally. I have been round and round trying to find a solution and have had...

Firstly apologies, I’ve posted quite a bit about this in the past but I’m at a loss and don’t really know what else to do. So here I am again , I’ve had some major issues with my 2004 4.0 Auto TJ that I’ve posted extensively about and had some really helpful conversations about , but...

Ok , so I know my mistakes , I didn’t do my research , went at my window bolts wirh force and stripped two of them completely out. The first two I done came out first try completely fine , the second ones however have completely stripped. To cut a long story short I’m now stuck with extractors...

Just putting a wee post here as kind of a conclusion I guess for anyone wirh the same problems as myself that stumble across this. As far as I can tell the jeeps fixed. How ? I don’t know. I know it wasn’t the o2 sensors I changed cause it still played up. What’s changed in the mean time is my...

So I’ve not got round to checking fuel pressure yet but I’ve been doing some research. After changing out the O2 sensors I had taken it on a drive about an hour away from home just to see what creeped up. Something that happened was the speed locked up and wouldn’t go any higher , can’t remember...

Ok so I eventually managed to source sensors and fitted them, and frustratingly they made no difference, it’s still stalling, I’m guessing next would be fuel pump , then pcm ? Im going to order a kit to test the fuel pressure to see what that says.

I guess its one of the joys of owning a tj in a country that grits its roads at the slightest hint of ice haha. The rest of the frame is actually remarkably clean and rust free, just the notoriously bad exhaust that's caught the worst of it. I had ordered an o2 sensor socket, but I had imagined...

Thanks for the tip, it's really helpful having all this help. As I had said I went from a 2013 Chevy hatch back to the jeep and it needed no maintenance, so having to dive into it so soon it's been a real help having so many people that live and breath jeep on tap. It's just a pain it's a hard...

Yeah I found Chris's post on o2 sensors , I presume export models will all be the same part numbers ? I can't see why they'd need to be different.

Thanks for all your help it's been a life saver, I'll try replacing the remaining O2 sensors and see what that does. If nothing else it'll save me doing it in the future anyway.

Do you think it's possible that the o2 sensors could me failing and just not throwing codes ? I'm guessing the only way to tell would be replacing them and seeing if there's a change. In my post I had said I didn't know if it's was something heat related as it had sat un driven for a while...

Its got just about 98,000miles on it

So I've climbed under the jeep today and it appears that only 1 post cat sensor was changed bank2 sensor2 , but it's an NTK one , and the plug is fully seated. The rest all appear to be NTK sensors also. I gave everything a good shake as someone suggested the cat may be loose but everything's...

Thanks for your reply mark, I've had a bit of contact with the previous owner last year but not since then , from my understanding he only really had the jeep about a year and sold due to having a job change and needing higher mpg for commuting, so that plus the pandemic I doubt it was driven...

I doubt I'll ever do 30k miles with the current fuel prices over here hahah at the moment it's costing me £80 to fill which I think works out to be about 110 dollars , it's nuts compared to the small Chevy I had before that took £30 to fill the tank and lasted 250+ miles , but it was nowhere...

I don't have a clue when they were last changed, I know jerry swears by autolite but getting the correct ones in the UK is sometimes quite difficult and quite costly. So ive got a full set of NGK ZFR5N ordered to get installed.

Ill check the brand that was installed as soon as possible. Do you think in your opinion something as simple as an o2 sensor could cause such the variety of issues I've been experiencing?

Ill defiantly check the o2 sensors as soon as possible, one of the main automotive part suppliers in the uk is called Euro Car Parts, and they state the Bosch sensors as a part for the 04 wrangler, and given the garage it had work done on it it in wasn't jeep specific and considering the rarity...

ill definitely need to get the kit to do it
