Not sure if you're coming back Mike, but here is something at least.

P0300
Random misfire detected Run engine steady > 2 minutes 2 Fuel contaminated
Fuel injector(s) blocked or leaking
Ignition secondary circuit breakdown(coils, spark plugs)
Fuel pressure low
Cylinder compression low
Broken valve spring(s)

P1314
Catalyst damage misfire detected cylinders 4, 5, 6 (B bank)

I would start with the coils, they seem to be a regular topic.
