First of all, consider whether the throttle has too much carbon deposit. If there is too much carbon in the throttle, cleaning the throttle can solve the problem. The main function of the throttle valve is to control the air intake, which will affect the fuel injection. As the air intake increases, the fuel injection will also increase. Therefore, the throttle valve is a device to control intake air and fuel injection into the cylinder. It is normal for the accelerator to have carbon deposits, because gasoline will produce anxious substances after burning at high temperature, and these anxious substances are carbon deposits. Especially when driving in cities, the carbon deposition of vehicles will be more serious.
