slight missfire, but I still have spark?

alright, I've got a missfire that seems to be getting worse. I've pulled the plugs to try and figure out which cylinder isn't firing, but they're all running so rich, it's hard to tell. I also checked for spark on each plug and everyone seems to be firing consistently. there's no arcing off the wires either. I've been working some long hours lately, and haven't had time to think this through too well. any ideas one what could cause the miss? anything that is maybe only making it miss every couple of fires?
