On February 0, 2009, Cheng Jing did not have a black smoke fault code.
This situation is generally a sensor problem.
If the engine emits black smoke, it is mainly the fault of the engine electronic control system. In this case, I suggest you go to the repair shop. A decoder reads the fault code to see if the data flow is normal, usually the sensor is faulty.
First, replace the spark plug, clean the throttle and nozzle, and see if the situation has been solved. If it is not solved, the oxygen sensor should be cleaned or replaced. The situation of black smoke is that the gasoline is not completely burned. Check the air filter, air flow sensor, fuel injector and gasoline pressure.
