Blistered Ignition Coil, Rough at Idle

Update on 04 Rubicon running rough and bouncing speedo...

I replaced the ignition coil, the coil closest to the firewall was blistered on top. Replaced all 6 plugs with Autolite Platinums...

Removed battery cable to reset the computer. Now I am getting code P 352, Coil B fault. Not sure which is Coil B... would guess its the one in the middle but the coil cloesest to the firewall is getting HOT within 1 min of running.

I am at a loss and I need help. This is my only ride and as of right now I am boring an extra vehicle of my brother in laws.

The speedo is still bouncing around while in park. The tach is not acting up.
