Hello! Brand new here, I made this account just to maybe help solve my issue. Like the title says, my jeep runs on a time limit. It sounds crazy right? Hear me out. I have a 1996 Jeep Cherokee, 4.0 Inline 6, Aisin Warner Auto transmission, 205k miles. Bone stock aside from LED headlights. Parents gave it to me and I've been driving it since it was at 160k. Hauled a boat for a decade, that's the most strain it's ever been under.

No CEL and no codes were ever thrown or presented through the duration of this entire rant.

My alternator died back in October and it took some stuff with it unbeknownst to me at the time. TPS, IAC, god knows what else. A night before it died, I was at a red light and once it turned green I put my foot on the gas and the car did not move. It revved, but barely even crawled, not even an idle crawl. After a second it started moving just fine and I made it back home. Alternator gets replaced and everything else is fine. After a week I had acceleration trouble and it started to shift really funky, like hanging at 3.2k RPM for three to five seconds before roughly shifting into gear. The rough shifting was somewhat intermittent and I put up with it for two months, I didn't know it was a bad TPS. I'd coax and baby it everywhere I went, I'd even slowly take my foot off the gas so it wouldn't buck when the throttle plate closed. I replaced that and the ignition switch and ignition cylinder around the same time, everything works fine to my knowledge. Ever since the alternator died my jeep's had a time limit. I can drive two hours give or take before a gradual decrease in power and trouble shifting, resurfacing symptoms of the TPS dying. I could drive to work just fine in the morning with no issues, but roughly ten minutes from my place on the way home I'd notice a slight hesitation to accelerate and trouble shifting on its own. I always made it home, until last week. I was ten minutes from home and it had trouble shifting and hard time accelerating, "normal" for me. I came to a red light and as soon as the vehicle stopped and the engine died. All electronics work just fine, the engine just gave out. I waited an hour once i was out of traffic before starting it in neutral and it fired up like nothing happened. I took it to a shop and they got no codes but they believed IAC could be at fault so I got that replaced. My little jeep worked like a charm...up until two hours ago. Same song and dance, shifting issues, a crazy hesitation in acceleration, I had to put my pedal to the floor to get 2k RPM and 40mph to limp her home. Of course the engine cut out as soon as I pulled up to a stop sign a block from my house. I waited half an hour and tried it in neutral to no avail so I got it towed.

What could it be? I've heard everything from operator error to transmission to MAF and MAP to wiring to send it to the scrap yard, but I really want to try and save this family "heirloom."
