Pulled out plug number three and it actually looks like the electrode had partially melted and touched the thing that overangs (not sure what thats called). This is my fault because in the summer I experimented by putting Copper plugs by champion in the car. I know they should not be in there. I forgot that I had those in there. The car did feel like it was running well with those but I guess it doesnt put up with stress as well.
