My cousin's 88Z was doing the same thing. It was sooo bad that if you let it idle in one spot it would stain the road with black soot. We changed to O2 sensor and gave it new plugs and wires, and that solved the problem, it also helped gas mileage.

His problem sounds a lot like the one that you've described amancuso! It leaves black soot all over the road.... so I think I'll tell him he needs to get it tuned up and change some things and hopefully it'll go away!!
