    miss fire

    Do you mean P0301?
    Could be stuck or clogged injector, valve sticking, vacuum leak...
    Fuel pressure.
    Is it during idle or above 3300 rpm? Can you hear and feel it or is it more knock

    What plugs brand and part number.

    Quick fixes are so named for how long they stay fixed.
    If you run out of gas, no matter which way you decide to push, the closest gas station will always be uphill and in the other direction. Corollary: The likelihood of running out increases when all of the nearby gas stations are closed.
    The parts shop that stocks part for Skylab II will not have parts for our year/model of Jeep.
    We cannot accurately judge the trajectory of a speeding critter (cat, dog, sasquatch).
