    Trouble Shooting - 1991 4.0 Manual...running rough to wont start

    I read through this when it was posted and I wanted to help but I'm not really sure how to. I was confused by the same thing, if it wasn't overheating I don't know why so many parts were changed to help with cooling. Then for it to randomly just die sounds like something else is going on...

    93 Wrangler 4 cyl 5 speed. Transfer case

    It is the NP231J, and there are some differences over the years. For a 4 cylinder manual, you need one with the 21-spline input gear. Meaning it needs to come from a 4 cylinder 5 speed or a rare 1988 6 cylinder 5 speed. 1987 6 cylinder were a different transfer case most of the time (NP207) and...

    1994 Hunter Green SE “Back to Stock” Thread

    Yeah, I fully agree. I have never elaborated on how/why I've been through so many mounts, but basically back in 2014, I was still a noob to everything automotive, and had recently done my SYE and installed a double cardan shaft built by a local shop. My tire balance had recently been screwed up...

    1994 Hunter Green SE “Back to Stock” Thread

    Well, good news. Apparently the distributor was off by a tooth. Not sure how that happened with multiple removals and restabs, but I checked TDC this afternoon and noticed the rotor was definitely not pointing in the right spot. No clue how I got that wrong last time I restabbed it, because I...

    1994 Hunter Green SE “Back to Stock” Thread

    Went by Harbor Freight and bought a fuel pressure test gauge. Sure enough, fuel pressure was perfect. I didn’t think it was a fuel problem but that was certainly a variable. It runs very rough. At this point I am thinking intermittently failing CMP sensor in the used eBay distributor, or slop...

    1994 Hunter Green SE “Back to Stock” Thread

    Couldn’t resist, I went out there and tinkered some more. First order of business was to pull the 1995 distributor and make sure nothing was wrong with it. I compared it to my old distributor which when last installed, ran fine. Only thing I noticed was that the oil pump drive was clocked...

    1994 Hunter Green SE “Back to Stock” Thread

    Well I decided screw it, try to fire it up. It fired up, but it runs quite rough and stumbles immediately when you hit the gas. Not sure why. I really don’t think I got the timing 180° out, because the last time I cranked it, it was a test run and I backed it into the driveway and then pulled...

    1994 Hunter Green SE “Back to Stock” Thread

    Pulled the distributor this evening. Nothing to report, I put the drill in the oil pump and it was pumping oil very quickly. Had I cranked the engine it would have been just fine. Of course, and had I not, I probably would have run dry again. Oh well, it was good anyways because I “upgraded” to...

    1994 Hunter Green SE “Back to Stock” Thread

    Yeah, I saw how nasty yours was. I have never ran tap water, so I have that going for me. I'm hopeful that a healthy dose of thermocure and Prestone will do it to clean mine up. The bigger thing for me is if my bearings/crank/cam/lifters incurred any damage by being run without oil. The lifters...

    1994 Hunter Green SE “Back to Stock” Thread

    Exactly how it went for mine. In 2020, I started spending some money and started with a lift, nice bumper/tire carrier, needed to drop the gas tank for that, don't remember how but eventually the entire interior was torn apart and the transmission was out for a clutch and flywheel and oil pan...

    Got a new battery a couple days ago. Needed this very badly - I tried to charge the old battery and all it did was get up to 11.5 V and then swell real bad and got super hot. I went with a Legend Professional from NAPA. Mother’s Day made it a tolerable price. I went with the stock Group 58...

    1990 YJ with a NP205 transfer case: what u-joint?

    You really should get rid of the Moog u-joint numbering and stick to the industry standard numbering. People don’t speak in 269, 369, etc. That is only Moog.

    1990 YJ with a NP205 transfer case: what u-joint?

    Mic it between the ears and mic the size of the cap. 1310 is a 3.219” dimension end to end and the cap size is 1.062”. 269 is not a u-joint size, that is a Moog number. Stick to the 1310 style numbering for less confusion. Don’t go based on vehicle.
