Your engine is toast. The black smoke indicates more than likely your valve seals are leaking oil into the combustion chamber or the piston rings are shot.
Time for a new vehicle...

In most cases it is the fuel filter. I don't know when it was changed before, but it should be changed at least every 8-10 k miles. Make sure you change the air filter too.

Black smoke could mean it is running rich, have a scan done, it is probably an engine misfire code and it will tell you which cylinder is misfiring. the last digit is the cylinder, unless it says random missfire, It may be time for a good tune up and don't forget the fuel injection system, Clean out the intake and do an induction cleaning on the injectors.
