I have a 2007 Wrangler JK, I think the model is the unlimited. It started misfiring awhile back and I changed the the plug, plug wires and coil pack. It ran right for awhile but it started again. 3/29/21 I bought another coil pack, from the dealer, and changed the plug wires again and it's still misfiring. This morning I pulled the plug wires from the coil pack one at a time and found the #2 and #5 pole on the coil pack were not firing. People, that think they know about working on vehicles, told me, it has to be the coil pack. Even after I changed it a second time. After putting a third coil pack, from the dealer on, I'm pretty sure its not the coil pack. So as it stands now, my jeep is misfiring, or not firing and I have a P2305 code. If anyone has ever experienced a problem like this or has an idea of what the problem might be, I would really appreciate your input.

 

A P2305 says it's the secondary of the coil pack. Since you seem to have beaten that dead horse, unfortunately it may be the PCM.
