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
