Excessive Black Smoke

Problems

Several things could be causing black smoke:

Cause: Dirty air filter (causing a restriction in the air inlet system)

Solution: Check the air filter, and replace it if needed.

Cause: Incorrect fuel spray pattern or extra fuel dripping out of the injector (causing the ratio of fuel to air in the combustion chamber to be too high)

Solution: Treat the fuel system with Diesel Extreme. Treat the oil system with Stiction Eliminator.
