    98 Jeep, TJ, 4.0, Automatic. >25 degrees F, starts right up runs like it's got 30,000 on the odometer instead of the 198,000 it actually does. 25 to 15 degrees starts but misses and have to feather the accelerator to keep it running for a few minutes then fine. <15 degrees starts, misses, dies, pops through the exhaust like out of time (guessing unburnt fuel hitting hot exhaust), dies, just can't keep running, will restart but just a repeat. I suspect a sensor is not doing it's job but which one would be most likely the issue?

    I would say change the plugs and maybe a new battery would help but idk

    If you can, stop at bout any auto parts store and have them plug into the data port. If it is just an easy to get at censor they may have one and show you where it is at.

    They would have accss to what the codes would mean if any.

    Yeah, I did the Auto Zone thing, the only code it showed was a misfire during start up. Hate to just start throwing parts at it but it's a bummer not being able to drive it on days like today.
