If it is any help, I had the same problem a few weeks ago with cylinder 4. My misfiring cylinder had a noticeable effect on engine operation, so it seems like my problem was more severe than yours. I couldn't see a defect on the spark plug so I changed the coil pack on that cylinder and it fixed the problem.

I wish I had thought about switching the coil packs to be sure of my diagnosis. The part was around $55 with shipping and I didn't like guessing that was the problem.
