This is not the answer, cats are fine and misfire still on the same cylinder... Change the plug on the missing cylinder, run for ten minutes, after cooling (VERY IMPORTANT) remove the plug and examine. if the sparkplug is totally clean, not even a burnt fuel smell, your injector is bad ! Change it and you'll be gravy :-)
