I has this issue, and threw the misfire codes.. It turned out to be my injectors; the dealership replaced all of them.. I think that the computer just reports the banks, not the individual injector failures, so they usually replace all instead of bench testing all of them..
My warranty company actually sent an inspector to the dealership to verify this, and the dealer showed them that bench testing would cost more in labor than a new set would cost, so the guy conceded..
