Running rich. Get a tune and that will fix your problem.

black smoke rich
blue/gray smoke oil
white smoke coolant

If that's happening, your bumper will show some carbon on it. It'll also wreck your paint there too. Ever see those riced up fart can ricer type cars with yellowing spots near their tailpipes or excessive blackening? Fix asap.
