Insufficient Ionization?

Midnight on a Saturday night and 100 miles from home the Jeep ('04-KJ-3.7) begins to misfire Now that I'm home (and learned how to check trouble codes) I find P0301 cylinder 1 misfire (as expected) and P2302, p2305, p2308, p2311, p2314, p2317 basically Ignition Coil 1-6 Secondary Circuit- Insufficient Ionization. What would cause a problem in all of the coils? At least its not a valve spring like I was dreading.

Well Insufficient Ionization means that we are down to Plugs, Wires, Coil, or even Fuel injectors.

1st i would check the plugs and wires to see if that is it. If not then Coils and then Fuel injectors. If none of that then Fuel filter ??/ Maybe?? But I would say plugs or wires.

Yep I'm changing the plugs now. They were due anyway, but I doubt all six coils went bad all of a sudden. Ill have the codes cleared then see what comes back after the plug change. But I'm guessing that it will turn out to be wiring or pcm related (because its all six coils).
