I have a 2013 JK with 3.6 pentastar that blew the #4 coil pack. It was replaced and all spark plugs on that bank were also replaced. Car drove fine for about 15 minutes before it blew the same coil pack again.
I replaced it again and checked the wiring loom for any obvious issues and also cleaned all the grounds. #4 coil pack blew again.
Coil and PCM was replaced, car drove fine again for 15 minutes of driving and it blew the #4 coil pack yet again.
Really stumped with this one. Going to have a better look at the loom but is there anything else that could cause the same coil pack to fail?
