Black smoke is usually fuel overload,gray is oil,white is water,your car is loading up on fuel,this can be caused by bad 02, sensor,s or catylac converter clogged,

Thanks T_S_T the guy thats working on it says he doesnt think its the catlac converter,he changed the fuel injector,had prob with it...we will see after its changed
