Look close at each coil pack for one that looks melted or has some bulging compared to the others. Sometimes that can tip you off to which one is bad.

Another thing to check is that your plugs are properly gapped. I had that problem on my car when I was in a hurry changing plugs one day and forgot to gap them properly. 4K rpm it started missing. Regapped them and it was good as new.
