Help with a P2314 error code.

[Soules3]

Having major problems with this code. It is also putting my engine in limp mode.

I have replaced the engine wiring harness
The ASD relay
The coil
And the spark plug

I replaced the plug because it appeared to not be firing at all.

Nothing

Any Ideas?

I assume you replaced all coils and all spark plugs
Have you checked out the computer yet
Some of these things like this can be tricky to run down and throwing parts at it is only costing you money

What year KJ do you have and what motor?

Proper spark plugs should be NGK ZFR6F-11G Gap at .040 inch.
This thread re P2314 should be helpful as well: https://www.jeepkj.com/threads/04-p2314-secondary-circuit-insufficient-ionization.51879/

Yeah, I forgot to add, I have replaced the PCM.

I run NGK plugs, and they are gaped .40. I didn't replace all the coils yet. As I just replaced them 1k miles ago, as well as the spark plugs.

Here is another thing I am wondering about. I read the other post and will give that all a try as well. Does the 2314 put the vehicle in limp mode. I can't really get a definite answer from what I have read.
