I pulled my plugs the other day to change them and when I got to the number 7 plug it was darker than the rest. It wasn't so dark that it worried me but the difference between it and the other plugs is noticeable.

Anybody have any ideas as to what this could mean? I've read that a clogged injector can cause this and mabye something to do with the valves, but I am not an expert. I have noticed a very faint ticking sound coming from the driver's side of the engine also.

Any ideas? Thanks in advance.
