I get this same thing every morning on startup. It's just unburnt fuel. I even have a big black stain on the wall in my garage since I park it in the same spot every day. Don't think it's too much to worry about.LLCoolJ94 said:I just spoke with Gary at Sound Performance, he thought it might be unburned fuel caused from a rich condition.
Further information is that the car was only running for about a minute, the substance appeared to be black, it did not smoke, and after a couple of "sprays" it went away. I have a catch can routed from the crankcase to the intake and a breather.
Does any of this information help to identify a problem?
