---Check for Carbon Tracks on the Spark Plugs and inside the Spark Plug Boots. These conditions will cause the Spark to bypass the Spark Plug and jump to ground on the engine.
--- make sure that the Misfiring Cylinder is getting Spark.

Let me know what you find. If you need directions for checking engine compression, let me know. Also, if you are getting a good blue snapping spark to the plug, you may have a partially plugged injector, sticking injector...
