You're going to have to determine the cause of the misfire. I would check spark, fuel and compression on all cylinders.

Maybe a vacuum leak somewhere? Did you plug in and pull any codes that may be present in the DME? What cylinder is misfiring? Did you try moving the spark plug into a different one to see if it follows?
