What are the symptoms when the throttle is broken?

Symptoms of throttle damage: 1, engine idle speed is unstable, high idle speed continues unabated, and engine start is difficult, especially cold start; 2, the engine idle speed instability or no idle speed; 3. The engine is difficult to start; 4. Insufficient engine power, poor acceleration performance and unstable operation; 5. The exhaust pipe of the car emits black smoke, which increases fuel consumption. If the throttle valve is broken, the vehicle will not catch fire. If it catches fire, it is a serious lack of cylinder. If the throttle is broken, it is recommended to replace it so as not to affect your normal driving. Pay attention to cleaning the throttle valve at ordinary times, otherwise it will be easily damaged.

Throttle cleaning cycle time: The change of throttle use state is mainly determined by air quality index, air filter state, vehicle use environment and driver's driving habits. Therefore, the cycle time of vehicle throttle cleaning cannot be simply determined by the mileage. When buying a vehicle, the interval between the first cleaning of the throttle must be the longest, and then the cleaning times may become more and more frequent due to crankcase ventilation and oil and gas condensation in the intake pipe. Generally, when the idle speed is unstable, there are tankers and speeding vehicles, and the throttle is generally dirty.
