Hey guys. Originally thought this was oil on this plug. Did a compression test and a leak down, everything seems in order. So now I'm second guessing what it is? Did the fire go out and fouled with fuel?? Might be weak or bad plug wire? I don't have an ohm meter at the moment. Car didn't miss that I noticed. It was a nitrous pass, and car fell off pretty good. Try the best you can with the pics I have. I didn't use a flash. All three pics are same plug. Just different angles. Thanks.
