A loose/old connector for the coil? Damn. That makes sense. Totally random, probably was happening every time the truck hit a bump the wrong way. Great work. I hope that was it.

I'm just seeing this. Congratulations! I'm very happy this truck is in good hands.

My fingers are definitely crossed for you. Did you take any interior pics with the black all in? I really would like to see how it turned out, but at the same time I have the feeling it will make me regret selling you the truck. I'm really glad you're taking care of it so well.

Very good news. Was the culprit the auto shutdown relay?

Awesome!!! My fingers are crossed.

If the ASD relay doesn't solve it, I'll send you the old distributor for the cost of shipping. Just PM me and I'll get an email alert and will get back to you right away. I've been busy lately and haven't checked the forum much and I have to be on here to get post notifications.

I had multiple issues at once which caused problems for me. First, the intake host for the fuel pump in the tank came loose so I basically ran out of gas when the fuel level went too low as the pump couldn't pump the gas. When I fixed that issue the truck came back running rough. I replaced the distributor at that point (for good measure). But then I discovered a bad O2 sensor and a crushed downpipe which were the real culprits for the rough idle. The distributor was likely fine. So there was nothing wrong with the distributor when I replaced it. I did have a hell of a time indexing it, though, as the timing marks on the harmonic balancer do not line up correctly when cylinder one is at TDC. I think the balancer has turned over time (remember I noted it was near end of life), making the timing marks inaccurate. It happens. If you yank the distributor, DO NOT rely on the timing marks - find TDC by probing cylinder one.

I was hoping that coil fixed your issue. I wonder at this point if the new distributor has a faulty cam position sensor. PM me if you want me to ship you the OEM unit I pulled from the truck. I still have it. The fuel pump will prime itself when you turn the key as lomg as it's not already primed (it will stay primed for about 5 minutes). You should hear it.

Yes, sellers do this too. I've experienced it and have wondered whether people are just too lazy to mark items as sold. It does seem too hard for some people to give the common courtesy of a short message or call when they no longer need/want/care about whatever the thing might be. You know me. I don't care. My dad always told me he didn't care if I liked him, but I damn well better respect him. Maybe that's where this is coming from. I'm expecting common courtesy from my fellow human beings and don't feel I'm getting it.

I've got a big gripe. Lately I've been listing parts and vehicles on various marketplaces like the Comanche Club classifieds and Facebook Marketplace. I've got a vehicle listed on FB, and over the past three weeks, I've had three people swear to me they're showing up the following day to purchase a vehicle, then they don't show up, and I never hear from them again. I can't tell you how many people have asked if the vehicle is available and when they get an affirmative reply from me, I never hear another word. Not even a "thanks, I was just wondering". I've got parts listed here on CC. Several times I've been asked for a shipping quote on an item and for pics. After spending the time to get weights, measurements, pics and a shipping quote along with replying to the requestor, I hear nothing back. Not even a thank you for my time or efforts. I'm tempted to list some members names here in some sort of "wall of shame", but I won't. It seems the younger the buyer is, the less they care about courtesy. Older buyers typically respond to messages quickly and show up when they say they are going to. Younger people just don't have the same manners (generally - there are exceptions like military personnel). It's really been annoying me lately. It take it as selfish. If I spend any time at all doing something for somebody (like issuing a quote, or replying to a message), I expect at least a "thank you, but I'll pass" in return. The cutoff for having decent manners seems to be 40 years old or so. Is ghosting sellers now the acceptable method for relaying disinterest? What feeds this behavior? Is it really the new norm cease communication to express disinterest? I'm feeling disrespected every time this happens, and I'm wondering what the heck is wrong with society that we let this kind of thing go without a fuss. I'm not sure what the purpose of this thread is other than to vent a little. Perhaps people could share similar experiences, or perhaps some younger members could explain this phenomenon, or maybe assure us that all is not going to hell in a hand basket. Maybe somebody in the habit of ghosting sellers will read this and learn their behavior is undesirable. Who knows. Thoughts welcome. Ugh.

When I got the truck, the A/C system was not fully installed. I installed all missing components with new components, including putting in a new compressor years ago. Check the compressor for the oil level, and adjust as needed. I'm not sure if that's right - use the right oil. Besides that, I would charge it and look for leaks. Also, I have OE mirrors if you need them. Left is a manual remote, right is fixed. They need paint, otherwise they work great. PM me if interested. Concerning the MC upgrade, seem unnecessary to me. It's using a YJ proportioning valve, and the LSV was deleted, and it stops on a dime. If you want to go back to using the MJ proportioning valve, let me know - I just found it, but I don't have the LSV any more.

This is correct for 4.0L manuals, and why I recommend 3.73 with 31s with thqt setup.

An 89 listed with a 4.0L High Output engine and an XJ15 manual transmission. Either the owner has no idea what he has, or there has been an engine swap and a typo.

You should be able to plug the 4.0L engine wiring harness into the existing body harness without issues. Jeep tried to make all that stuff as interchangeable as possible. For example, in the previous generation (YJ) during the 1991-1995 high output years, the only difference between the 4.0L and 2.5L engine harnesses were wires for two injectors (whuch could be spliced in), and a power steering sensor (used on the 2.5L only to increase idle when turning the wheel when stopped). So your chances of that 99 TJ harness just plugging in and working tight are really good.

Coil is suspect due to age (~140k). Entire distributor was put on (new cap, rotor, cam position sensor) was installed within the last 100 miles. Plug wires are really nice and were installed within the last 1000 miles.
