 To track down rough running, you will need to eliminate variables.  Dry the plugs.  'Best would be to have all four in as nearly the same condition as possible.  With dry plugs, move on to spark.  Check to see, as best as you can anyway, whether the spark is nearly the same strength at the plug end of each plug wire.  If you find a weak spark, try swapping wires and see if the weak spark follows the wire or stays in place.  If a weak spark stays in place, well, all sparks originate from the same source so something between the coil and plug wire is suspect, like cap problems.
Good luck!
