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.
