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

If the throttle valve is broken, the engine will be unstable at idle speed, and it will be difficult to start the engine at high idle speed. Especially the cold start is difficult, and the engine idle speed is unstable or no idle speed; The engine is difficult to start, the engine has insufficient power, poor acceleration performance and unstable operation; The exhaust pipe of the car emits black smoke, which increases fuel consumption.

Cleaning cycle of throttle valve

The change of throttle usage mainly depends on air quality, air filter status, vehicle use environment, driver's driving habits and other factors, so it is impossible to simply judge the cycle of vehicle throttle cleaning by mileage.

When buying a vehicle, the interval between the first cleaning of the throttle must be the longest, and then the cleaning frequency will become more and more intensive with the factors such as crankcase ventilation and oil and gas condensation in the intake pipe. Generally, when driving, there will be situations such as unstable idle speed, oil truck and acceleration truck. Generally, it is caused by dirty throttle.
