What does the O2 sensor activity look like, could be a bad bank 1 O2 sensor, or maybe injector ground on that side or you could have a plugged cat on that bank. Seems like all of bank1 (except for cyl 1) is misfiring...you could try swapping the O2 sensors side to side and seeing if the misfires follow...
