White smoke could be just condensation but if it continues be concern, as for the blacky you're running too rich could be caused by the following

A bad O2 sensor, excessive fuel pressure (bad fuel pressure regulator or plugged return line), leaky fuel injectors, dirty air filter or restricted air inlet, or a defective coolant sensor that prevents the engine management system from going into closed loop mode.
