I was driving my wifes 99 today. When i get on it i get a little black smoke which is normal. When i get off the pedal(quickly) loads of black smoke? why?

Black smoke is just from overfueling/unburnt fuel.So when you let off quickly from accelerating there is still a increased amount of fuel pumped into the cylinders for a short period of time while the engine is slowing down. Just my thought on your situation i could be wrong but it defantly deals with your amount of fuel in some way

i just paid attention to mine in the mirror while shifting gears (i have a 6spd manual)... and it does the same thing...no problems though, i like the black smoke
