The black stuff was most likely a result of the engine running rich.
Does it try to start? Have you checked to see if you are getting good spark? Also, have you checked fuel pressure? Finally, behind the throttle body, there is a vacuum line with a 90 degree bend in it. Make sure it isn't leaking. They commonly break and cause problems.
Let me know what you find.
