Pretty hard to tell with no other clues or observations. Black smoke is a result of too much unburned fuel. That can be caused by a problem or it can be a result of the Engine Computer requesting too much fuel in response to an incorrect sensor reading. Normally there will be a diagnostic fault code and when an increase in emissions is involved, the Check Engine light should turn on. Have you checked for fault codes?
