    no codes? thats odd with a miss usually that will set a miss fire code.Did you pull the pulsator off the fuel rail and look for rust?That could cause missing from small particles of rust floating around the fuel rail.Ask me how i know????

    The injector can cause that one cylinder to go lean...busted head gasket near that cylinder.
