yup, way rich AFR 1st guess. High carbon deposits/blowby in the combustion chamber...what engine u got? mileage? mods?
scratch that, slight possibility the gas u use is poor quality but its GOTTA be the air/fuel ratio, clogged air filter, bad ignition timing, overcooling, stuck on open loop. Boost controller turned 2 high?

Having excessive black smoke with tar forming on the bumper is a sign of running too rich. If you have any chips piggybacked onto the PCM, take them off.
If your car has been tuned, get in contact with whoever tuned it.
