What will happen to the car if the throttle is broken?

Engine idling is unstable, there is no idling state, the engine is difficult to start, the power is insufficient, the acceleration performance is poor, the exhaust pipe emits black smoke, and the fuel consumption increases.

1. Unstable engine idle speed: When idling, the tachometer pointer fluctuates up and down, and the idle speed is higher than normal, which makes it difficult to start the vehicle, especially during cold start.

2. No idle state: When the throttle valve is damaged, the engine may not be able to maintain a stable idle speed, or even there is no idle speed at all, resulting in the vehicle being unable to run normally.

3. It is difficult to start the engine: the throttle fault affects the airflow, making the mixture too rich or too thin, which makes it difficult to start the engine.

4. Poor acceleration performance due to insufficient power: damage to the throttle will affect the intake of the engine, resulting in insufficient combustion of the engine, resulting in insufficient power of the vehicle and decreased acceleration performance.

5. The exhaust pipe emits black smoke, and the fuel consumption increases: due to insufficient combustion of mixed gas, the exhaust pipe emits black smoke, and the fuel consumption increases obviously.
