    ok, could be a bad plug or wire but you need to start at basics. with this condition, it may not missfire in a sense that you can feel but needs to be checked anyway. after the compression test, fuel pressure, spark and vacuum leaks are next.

    If you are receiving misfire codes 301, 304, etc perform the basic plugs and wires. If after you install the plugs and wires you still get a300 check your crank sensor most likely that your problem.Let me know if that fixed your problem.

    The Jeep has no code for misfire but that's exactly what it feels like or like it is very slightly out of time but no codes....?
