got a PO356 code back from Lund, I somehow missed this but it's an ignition coil circuit code for cylinder number 6. Of which is on bank 2

A vehicle’s PCM could log a P0356 code for a handful of reasons:


The (COP) could simply be faulty
Coil #6 could have a loose connection
Coil #6’s connector locks could be broken
The COP driver circuit is open
The COP driver circuit has a short to voltage or is ground
