Hello, I started having issues with Bank2 fuel trim deviating to far away from bank1 and throwing MIL for misfire on all of Bank2.

Is there a different ignition controller for each bank? Different injector controller for each bank? The spark plugs looked great on both sides. I am a little lost trying to chase this down and don’t want to have to take it to the dealer if I don’t have to.
