u have a turbo going bad ,check again when u first start car in the morning ,u should see smoke again ,also u need to get your o2s sensors check for proper function ,black smoke is may be poor fuel to air mixture ,meaning poor o2s sensor operation ,but could also be other issues ,start there .good luck.
