Well, you are DEFINATELY running too RICH with FUEL! This canbe caused by MAF sensor or TEMP sensor or something else. Is your service/check engine light on?

You also could have a leaking/bad fuel pressure regulator. It leaks raw fuel into manifold making overfuel condition which would produce black smoke. Take off vaccuum hose to regulator and check for wetness/gas in hose.
