Here is what shot out of my exhaust when the engine shuddered and gave me the 3100 code yesterday. Saw it when I was walking back to my apartment this morning. It's not really an oily consistency, more like a dust or carbon buildup feel to it but it was strange it flew out like the car shat itself. This could be unrelated, but I thought I should post it up anyways. (Pictures are rotated sideways for some reason)
