Is it still under warranty? From the looks of your pic, you have an 05+
It's all the dealership problem now. Make them pay. It's your right as a consumer. Just remember, these vehicles are made mostly by people, with thousands of parts,
#$%^ somtimes happens. Sorry to hear about the problems.

You're getting a code of 2308? I didn't realize they went up that high.

You might could try switching the coil pack on cylinder number 3 with one of another cylinder on that side of the engine, and see if the problem moves with it. If it does, that tells you its the coil pack thats gone south, if not, well I think you know the answer.

BTW, how many miles do you have on your KJ. And it is an 05 correct?

With only a grand past, I would think you could have some working room there, if you start complaining right now, and I mean really complaining.
Take it to a 5 star dealer, point out that these items shouldn't break down at just past the warranty, make claims of fraud, and faulty workmanship, even going so far as saying that the dealership and mechanics put on faulty parts, make a stink in the showroom, and they'll give you whatever you want.

I just went and looked up the code on my OBD-II scanner and the code P2308 stands for Ignition Coil C Secondary Circuit.

Sounds like you might need to replace the main ignition coil.

I finally figured it out, thanks for all the info guys. Ended up being the coil having moisture in the boot. I took number 3 out and just cleaned it up. Works like a charm now....

So a little wet caused the error, good to know for the future.
