Bought a 1995 jeep last weekend, ran great all week. This morning I used the posi lock to put into 4 wheel drive and this engine dying problem started. Not sure the engine dying is related to using the posi lock, however someone mentioned that “when the Posi-Lock was installed that (if) the person installing it didn’t cap off the lines to the CAD system properly and he inadvertently disconnected the map sensor. That will darn sure cause it to run rich.” It does seem odd that this problem has started after I engaged the posi lock today. I’m also wondering (hoping) if it could be something as simple as a dirty fuel filter, but because it ran great last week, I'm thinking that's not the case...? When I bought this jeep, the seller told me he had a problem with the jeep dying and then starting up again. He said he’d found a wire that was shorting out and fixed it and the problem stopped. I assumed this to be true as the jeep has been running fine this past week, until today. What is happening is that I feel a ‘hiccup’ in the engine and a few minutes later I lose the ability to accelerate or rev the engine and the engine slowly powers down and dies. When this first happened this morning after using the posi lock, the jeep would start, then die, start, then die, before I could even get it into gear, and then finally the engine stayed on and I was able to get it home. An hour later, I took off into town, made it about a mile down the road when it hiccupped and started losing power again. There I sat on the side of the road trying to get it to start and it wouldn’t turn over. I popped open the hood hoping to see something obvious like a loose spark plug wire perhaps, but no. I got back in the jeep and it started. There is always a strong smell of gas when it starts up again after these episodes. It died again a mile later at the entrance to my carport, but started 5 minutes later so I could get it into my carport. It is a 4 cylinder, 5 speed with a carburetor. Anyone had a similar experience? I plan to have this baby fo' eva and am willing to fix whatever is wrong with it. I'd like to give my awesome mechanic a few ideas of what he might look for so I'm asking for ideas/input. I'd like better to fix it myself if it might be something simple...I have a Leatherman multitool (that's a joke). Thanks, Kat.
Got my question answered on another thread..."When they installed the posi the vac lines were not properly removed or capped." Hopefully if I don't mess with the posi lock, the jeep will run fine again until the posi is fixed.
Well, so much for the posi lock theory. That ain't it. Took the old girl for a drive today and she stalled 3 times, the last time she wouldn't turn over. Tow truck called, Jeep at mechanics shop. I just bought this jeep last Saturday. Seller claimed it ran just great. I'm all willing to do the necessary mechanical upgrades, but was hoping to fix stuff as time and money allowed, not within a week of buying it. Geez, I hope I didn't buy a lemon. Are there any jeeps that are lemons?...that just never run 'right' no matter how much $$ one puts into them? Please say no. Got the used car blues tonight...but DANG!...I sure do like that Jeep!!
Hopefully it's something minor like a clogged fuel filter. Sometimes when you buy one that the PO hasn't taken very good care of, it takes a bit of time and money to get it road worthy. I had to rebuild the engine in mine 3 months after I bought it. The first year I owned it I maxed out my AAA tows, lol. I figure that the more I have to do to it, the more I know has been done right.
Thanks both of you. I'm feeling better with the ideas that it might be something simple. I'm really thinking that it is. This little episode with my jeep today is making me relive the horrific memory of owning a Mercury Capri in 1982. And thanks, CindiB, for the humor! The 'maxing out' of my AAA roadside assistance with this jeep did cross my mind tonight. lol !
I should clarify my earlier post by saying that I knew my engine had serious issues when I bought it, so the rebuild was not totally unexpected. But this forum is loaded with "won't start" and "keeps stalling" threads, so they're common Jeep issues, especially with the carbureted motors. I think it's a good thing that you're having your mechanic check it out. Welcome to the addiction!
Im also going to side with the other 2 fellers that posted on here. That sounds about right. Been doing this mechanic thing for a little while now. I have a 89 YJ, and mines basically totally stock...being in the service, and away from my Jeep didnt allow me to tinker . I see me fixin basically everything on it.
