Here is the situation :
The black smoke came out of exhaust ONLY when reving the engine up and down , but when accelerate and hold it , there is no black smoke .
Every one says check the sensors , injectors or regulator , but I think there is an evidence it's related to an incorrect ignition timing .
My question is , does the black smoke has any relation with the timing of sparks ?
I assumed it because at high engine speeds , the sparks automatically advanced .
