Missfire in cylinder

well ive come to a conclusion that one of my cylinders is missfiring. I replaced the spark plugs and ignition cables and see if that fixed the problem, but it didnt. i think there might be something wrong with my distributor, but does anyone have any other ideas what could be causing the missifre before i start worrying about my distributor? thnx

is there anyone that can help me with this?

did you replace the cap and rotor when you did the plugs and wires?

sounds like a distributer problem
