    I ACTUALLY GOT IT FIXED LOL!

    So, what happened was the injector wiring for the #1 injector got bumped at some point and the wires were knocked loose INSIDE the crumbling boot. I plugged them back in, RTV'd the crap out of it, and she's running like a dream now.

    Hope your feeling better and are ready to go at it -
    STOP GUESSING! STOP clearing the computer -
    OK drivability first deal with clunk later.

    Is jeep driveable? 1993 is a tough code retrieval not the quick scanner they are rare for OBD1,
    Copy ALL numbers and post.
    We will tell what code means. Subtle differences from generic list.


    QUOTE "The code says injector fault, but all my injectors are good,"
    what was this code - AND how did you check injectors?
