Car's recently started running a little rich. The weird thing about it is that it only seems to puff black smoke only during a launch after a long idle (say a red light; small vibration during idle as well) and it also goes away after a while. What do you guys think might be the culprit? Will be checking the MAF and my intake as well as a check for vacuum leaks

Edit: I've replaced the distributor, spark plug wires, spark plugs, and valve cover gasket so I doubt its going to be the spark plugs
