Black smoke indicates a rich fuel mixture. Have you checked fuel pump pressure to make sure the regulator isn't allowing too much pressure? Have you checked to make sure there are no leaking fuel injectors? There are several sensors that can cause a rich mixture too. Has the check engine light come on?
