Hi fellow jeepers, For the past year or so i have been facing issues with my TJ (1997, 2.5l, manual) and i ve been hoping i get your advise of what might be based on the info below 🙏 On random occasions my jeep starts jerking and bucking and missfiring. It can happen after a mile of driving or...

Hello, have a little bit of a strange dynamic. I have high oil pressure. I don't know what the ranges are off the top of my head but it goes from like 2.5 to 5. It started recently pinning to five on throttle and then going down to 3.5 slowly when I let the throttle off so when I'm throttling...

Hey y'all. New guy here. This is my first time to actually own a Jeep and not just mess around with a friend's. Found a good starting platform, but she needs a few things of course. I searched the forum and it seems like I may have the typical timing chain/tensioner noise on my 2.5L engine...

So I'm in the middle of replacing the clutch, clutch components, and RMS on my '98 SE (2.5L / AX-5). As I was cleaning the oil pan and back of the block, I noticed this "thing" on the back of the cylinder head was semi-popped out. I asked my coworkers what this was and they said it was one of...

97 TJ 2.5 Rebuilt the engine. Everything is back together. I can't find where this plug goes. I had 98% of all connections tagged. This one wasn't and I don't know where it goes. Engine is cranking over but wont fire.

Hi all, Someone stop me if this already exists, but I haven't found it, so here we go. If I keep this updated well enough, it can be a place where we collect links of relevant threads, and also the names of other members who are in this same SE boat. General, Reference Info: 2.5 vs 2.4...

Good evening Jeep experts. Jeep rookie here. Was trying to find a thread that was close to my problem. 1998 TJ 4.0. 51k miles. Was miss firing and throwing a misfire code, reset that code, continued with a new code misfire multiple cylinders. Changed all plugs (they were original plugs) with...

2002 2.5L. Headgasket/head rebuilt July 2019. Since wheeling season around here ended in December the jeep has been sitting on its trailer and only been started once in February. At that time there were no issues and it ran normally. This past weekend it was pulled off the trailer in...

Hello everyone! My name is Eric and I recently moved from Eastern NC to the FL Panhandle for work. I had my quarter life crises and bought a 1998 SE almost 6 months ago. Let me tell you, I've been loving every minute of it! It's my first Jeep, first time driving manual, and will be my first...

Hi All, So I'm in the market for a new front driveshaft for my 1999 Jeep 2.5l 4cyl. On all the websites I can only find front driveshafts for a 4.0 I know that the auto ds and the manual ds are different but are the 4.0 and 2.5 ds different. If anyone knows if the driveshafts are interchangeable...

I am currently running 31s on my TJ 2.5L 3 speed automatic, and the previous owner didn't regear it correctly. I was going to regear it anyway, but I was wondering if it is possible to go up to 33s or even 35s with the smaller engine. Also, what would the gear ratios be like? I've done a bit of...

My girlfriend’s Jeep is a 2000 2.5 L auto. Lately whenever she comes to a stop it feels as if it is going to stall, even though it is an auto. When she goes to press the petal she said that it feels like trying to start from second in a manual. Almost as if the motor feels bogged down. I suspect...

I'm new to this forum but have used it for about a year. I'm a freshman in college so funds are low but whatever isn't used on food and school is used on my jeep. Her name is Rooster because when I got her she didn't have a working horn which turned out being the relay. I bought a relay, she...

After test driving a 97 tj se with the 2.5 4 cyl, im not sure if i should opt for the 4.0. The 4 cyl did not seem too bad on power, but i cant exactly compare to the 4.0 as i have never driven one, and dont know if the 2.4 would be worth it over the 2.5. Are the other upgrades to the sport (what...

I know that the best upgrade for any 2.5 4 cyl is to replace it with a 4.0. That's not really in the budget for me right now and I'm sure there are people wheeling 2.5s. Short of the 4.0 swap, are there any modifications that you have made to your 2.5 motors to give them a little more pep and...

Hello Everyone, About a month ago I purchased my very first Jeep. Ever since I was a kid I knew I wanted a Wrangler. Due to funds and circumstance, I have driven Toyota Corollas my entire life. Once my 2004 Corolla needed a new catalytic converter, I decided that the time to drive a jeep was...
