What are the symptoms of the eighth Accord when the accelerator is broken?

The main symptoms of throttle fracture are: the engine is unstable quickly, the high-speed discontinuous descent, and the engine is difficult to start, especially the cold start; Unstable idle speed or no idle speed; The engine is difficult to start; Insufficient power, poor acceleration performance and unstable operation; The exhaust pipe of the car emits black smoke, which increases fuel consumption.

Throttle is the throat of automobile engine, and it is a controllable door to control air to enter the engine. The depth of stepping on the accelerator is directly related to the opening of the accelerator, so the performance of idle speed (engine revolutions) and power (speed increase) is closely related to the cleanliness of the accelerator. Generally speaking, the throttle valve is a door that controls air to enter the engine. After air enters the intake pipe, it will mix with fuel to form combustible gas and burn. It connects the air cleaner and the engine, so it is the throat of the engine.
