    I suppose after changing thermostat if gauge doesn't change that the sensor may be bad. I'm not sure where the sensor is or what it looks like. May even be two sensors. I don't know

    Just another thought. Since you are getting multiple codes, there are two issues you might want to consider. One is bad grounds. Redo them all. Second is the ECM. But of the two, the grounds are the most likely

    stalling and back firing became worse. One code showed up as bad ignition coil. I replaced ignition coil and disconnect battery to reset computer. Temperature is still low. I plan to replace thermostat next because temperature runs below normal operating temperature which I assume would cause engine to run rich.

    Argghhh!!! I'm beginning to hate Jeep. I replaced ignition coil and rotor button. I put in a thermostat as there wasn't one in it. And it still backfires and stalls out.

    This pos is really ticking me off. Two mechanics said nothing wrong with it. It keeps back firing and stalling out. No necessary at same time. It seems sometimes backing out of accelerator or lightly pumping it may prevent a stall. It's starting to not start right back up but will after time passes. It has stalled out after driving it for awhile and immediately when started (cold). If it were legal I would I burn it to the ground. Not getting much help here either. I'm nearly to the point I would never buy a Jeep product. There should be a class action law suit. I had to get pushed from a redlight to the store and it immediately started. WTH???

    So reading through your thread, it looks like you've replaced the cat, muffler, thermostat, plugs/wires, rotor, ignition coil, etc. and you still have a backfire/stall problem. I'm wondering about the condition of your throttle body. You can pick one up from the junk yard for a decent price, or try rockauto.com for great prices as well.

    I'm also wondering about vacuum leaks, O2 sensors and sensors like CPS, TPS, and their connections/wiring. One way or the other, we'll try to get this resolved for you buddy.

    Whatever happened with that distributor code? If something is off with the distributor it certainly might effect the timing which could cause the backfire and stalling.

    Jeep shut off last night and two night. Mostly @ red lights. It seems like it worse during colder temps and wet climate i.e. cold, ice, early mornings in Florida. Last night was worse than tonight and
    I had ice on windshield yesterday. It tried to die last night at a stop sign and I placed it in neutral as it tried to die out which prevented it from stalling. I may have slightly revved accelerator. revving slightly or backing out sometimes prevents or prevents it from stalling out.


    I called Auto Zone about fuel filter and was told it is 112.00 for fuel filter which is also a fuel regulator according to Auto Zone. Please help, I recently became re-employed which means I'm on job probation. I can be let go for tardiness or car troubles and attendance.
