Now to puzzle out the cause. The above posts are great starting points. Since it is a single cylinder, it has to be one of the following:

Missing spark: one of your plugs, contacts, wires is wonky
Fuel: An injector is misbehaving, leading to lean conditions

As mentioned above, it looks like lack of spark due to the buggered contact. Yeesh, this is ugly:


Not sure if the contact is the cause or a symptom of another issue manifested on the cap, but in case it is just operational corrosion, this is why dielectric grease is a nice addition to these contacts to keep moisture/air away from highly charged parts. It provides a barrier from the atmosphere that decreases the liklihood of accelerated oxidation due to the electrical charge passing through the part.
