Q: Check engine light/emissions workshop! blowing black smoke while accelarating, among other acceleration issues.

Hello. Black smoke is usually the result of an excessively rich condition. The black smoke is a result of excessive fuel from a rich condition that was not burned in the combustion chamber, burning up afterwards, in the exhaust pipe, and producing black smoke. This can be caused by many things. If the Check Engine Light is on, I would recommend you have the trouble codes retrieved to see if they may shed some light on what the issue may be. A few common causes of black smoke are afaulty fuel pressure regulator,faulty injectors，或引擎管理系统的问题。如果燃油压力调节器或一个或多个喷油器失败，则可能会进食发动机，从而导致富含燃料。拥有一位专家机械师，例如您的机械机器人，测试车辆，然后万博体育入口诊断烟雾和加速问题so that this can be properly addressed.
