I pulled my plugs and the 2 and 3 cylinders were still new looking, just looked a little worn. The 1 and 4 Cylinders were all black (even the threads) with some kinda stuff that i just wiped off. The #4 cylinder had a little bit of oil residue around the washer on the plug. I am hoping that nothing is wrong. Could there be something to cause my #1,4 cylinders to be black and the #2,3 cylinders to be shiny still?
