2.5 engine

Dear fellow wrangler enthusiasts, I've purchased my first wrangler a couple of weeks ago; 1998 TJ, 2.5 L, 5 speed manual gear and it's pretty much stock, apart from some exterior parts. Whilst test-driving, there weren't any apparent issues with the engine. A few days after I bought it though...

This thing is driving me nuts. My symptoms are a low/rough idle (sometimes sounds like it’s about to die). Also occasionally while driving usually happens around 2.5-3k rpm with about 1/4 throttle it starts stuttering/jerking very badly and if I let off gas or floor it, it quits. I have...

Can anyone recommend a leakdown tester that for sure comes with the right adapter to fit the spark plug sockets on the 2.5L engine? I was going to get the OTC 5609 https://www.amazon.com/dp/B0030EVL60?tag=wranglerorg-20 but alot of the reviews say it doesnt come with an adapter that fits the 4.0...

Howdy! I just finished replacing the timing chain on my 2.5l and about a week after reassembly, the belt started to squeal. I noticed that it didn't matter the outside temp, but mainly happened when the car was at operating temp. It has an intermittent tea-kettle like squeal that will last about...

I blew up my 2.5L four banger and re built it on a fresh block, but the problem is it doesn't run very well. when I have a video ill put it up. i has a check light (like usual) and I'm gonna scan it and figure it out. I have a theory that the rocker arms are over torqued though edit; idles...

Same part for 2.5 and 4.0? Mopar 5604 1030, Distributor Ignition Pickup Amazon link: https://www.amazon.com/dp/B0049EIMTY/?tag=wranglerorg-20

I do not own a wrangler... What I have is a 1991 Cherokee XJ 2.5L manual 5 spd, no abs, no a/c, no rear wiper, crank windows, manual mirrors, manual seats, and idiot lights and no tach, just the dumb shift light that thinks it should be a 6 spd lol. and she had 094k when I bought her. Ive put...

2001 TJ SE, replaced heater core, putting dash back on ..can’t recall where these are connected on odb 2 or separate

Starting a thread to discuss/investigate some intermittent engine stumbling/staggering issues I've noticed after I bought this TJ with regards to possible compatibility issues with having a PCM from a TJ with an Automatic As per @RMETeeJay 's suggestion I've started a new thread here to post...

2002 2.5L Automatic, not really looking to pour a lot in but just curious! I have done some reading on forums and stuff, I am not quite comfortable with regearing in terms of what it means and putting the money into it, but I'd like to slightly lift it and get bigger tires. Tires are just under...

Hello, the engine in my 98' TJ 2.5l blew in the beginning of September and was swapped with another rebuilt 2.5l from a 92' YJ. I was able to get everything together and technically running with the 98' distributor, but it did not run well. I also tried the 92' distributor and it cranked a lot...

What’s up TJ fans! Newbie here….I was looking over my sons 1997 TJ this afternoon and found this “arm” or “bar” to be broke. What the heck is it? I can’t find it in any diagrams.

So I bought my Jeep ten plus years ago and when things go wrong it’s typically because they haven’t been changed since I bought it. I do the regular maintain every other week but when things go exceptionally wrong more times then not, it just hasn’t been changed in ten years. My Jeep started to...
