Black smoke is usually an indicator that the engine is getting too much fuel and it is not burning completely, leaving the black smoke. Blue smoke is usually oil.
Try replacing the fuel pressure regulator. It is located under the doghouse near the air filter pan. Unless you have small limber hands you will need to move the air filter pan to the left as you ar facing it, to access the 3 (three Allen screws which secure the regulator. Move that pan or you will experience plenty frustration.
