Im having some more issues, shocking, right!?!? Was doing some medium pulls just checking some things and I heard a bang and got 30A4 5 and 6 codes. Limped it home popped good and saw smoke from cylinder 6 and coil popped out a couple inches. Coil was melted. Swapped newish coil and plug and went to work trying to diagnose issue. Seems it’s deactivating bank 2 and frying cyl 6. I just had mosfets replaced and everything has been fine for a couple thousand miles, long trip to NC. Anyone else have these issues, maybe she’d some light on it? Maybe my ignition system is bad? What tests to run

What do you call the wiring harness and such that connects all the coils. I’m looking online for it now and can’t even get that info
