    Less so when you have great guidance. I appreciate you all!

    96 XJ stumbles then shuts off when warmed up. P0171

    Update: Found a '96 at the junkyard near the office I had to visit, and the connector was still on that one so I pulled it. Replaced my halfassery with that connector, and now I can't get it to stall for trying. I still need to get some other items like the blower motor and washer pump...

    I'm not 100% sure it's resolved as of yet. Looked like there was some kind of impact to both wires at some point after they aged and became brittle. A lot of the strands were broken, though still touching inside the insulation. I trimmed about 5" off of each and spliced in a fresh section of...

    I couldn’t find anything even remotely suitable to replace locally yesterday so I decided to see if I still had splicing and soldering skills. Reassembled and working. I haven’t had a chance to give it a test drive just yet. Hitting junk yards while out of town this week. This is pre shrink and...

    This connector is discontinued, and I'm striking out even finding the terminations to repair it. Any ideas?

    Been staring at the FSM all day trying to figure out what the BK/OR wire is in that post you linked. I can't find anything in the fsm that shows that wire at G101 on the side of the block. Any ideas what it goes back to?

    You know, I spent about an hour trying to find that last night, couldn’t remember where I saw it. Thanks!

    Well Crud! Another '96 XJ with an Intermittent Stalling Issue

    My vote is on there being a curse on the 96 because someone at the factory got fired and called their brujo. Now we all gotta suffer.

    Started in on the grounds. Found the stud in the block loose. Nut was tight but stud was loose, and wires are crispy. I’m going to just replace all the ground cables and connectors and see what happens next.

    Oh, we have it all down here on the bayou.

    Agreed, finding time and adequate bug spray for the task is the next hurdle. Mosquitoes down here need tail numbers.

    PCM A4 is the best reference to test continuity to ground, correct?

    I actually traced those two, they're clean as far as I can see. I think one of the original owners had an issue and corrected it. I reterminated that one and replaced the ig switch (again) and the issue still exists. Need to check the integrity of the ground at the dipstick tube again. This...

    I've been afraid I'd have to open the loom, but it seems like the only logical next step here. Should be fun.

    CMP as in camshaft position sensor? I’ve replaced both the crank and cam position sensors - twice. I’m down to wiring now. I really don’t know what else to look at. Everything I’ve tested comes back within spec, hot or not. I’m bald, but right now I want to grow hair just so I can pull it out

    I thought so as well, but changing it only works until I move it. Something is telling the pcm to cut the spark. I have pressure at the rail, didn’t get a chance to check injector signal with a noid light, but verified no spark. I need to verify the sensor ground to pcm a7 tomorrow and figure...
