Suzuki Tianyu's throttle position is always open.

The throttle valve is located in front of the manifold and behind the hose. Throttle is a controllable valve that controls air to enter the engine. After the air enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, which will be burned to do work. The phenomenon that the throttle valve is damaged is:

1, the engine idle speed is unstable, and the high idle speed drops discontinuously.

It is difficult to start the engine.

3. The engine has insufficient power, poor acceleration performance and unstable operation.

4. The exhaust pipe of the car emits black smoke.

5. The engine fault light is on.
