f150 4.2l p0302 code only
 

replaced coil pack plugs wires all from ford still missfire on cyl 2 only drives fine when od is off , but when shifts to od missfire is more pressent and then it is windy out side.. HELP :confused::mad:

But clearing the code doesn't fix the problem.

The misfire may not be caused by a bad ignition part it could also be a fuel injector, or a compression issue or deposits on the valves and the head and so on.
I would listen to the fuel injectors with a stethoscope or something. I would run a fuel system cleaner like "Techron" and I would look at the Throttle body and the EGR system.

Good luck
