What are the symptoms of bad throttle?

Symptoms of throttle damage are as follows:

1. Engine idling instability or no idling: engine idling instability makes it difficult to start the engine, especially during cold start.

2. Insufficient power: it is difficult to start the engine. The starting engine has insufficient power, poor acceleration performance and unstable operation.

3. The exhaust pipe emits black smoke: the exhaust pipe of the car emits black smoke, which increases fuel consumption. Clean the throttle valve at ordinary times, otherwise it will be easily damaged.

Cleaning cycle of throttle valve:

The change of throttle state mainly depends on air quality, air filter state, vehicle environment and driver's driving habits, so the cycle of vehicle throttle cleaning cannot be determined simply by mileage. When buying a car, the interval between the first throttle cleaning must be the longest, and then with the crankcase ventilation and the release of oil and gas in the intake pipe, cleaning will become more and more attractive. Generally, when there is an unstable tanker on the road, accelerate the car. Generally, it is caused by dirty throttle. Prolonging the cleaning cycle of the effective throttle: Because many factors are uncontrollable, we should first try to reduce the idle time of the vehicle, and try to control the shift time of the manual transmission vehicle at around 2000rom/min. In addition, try to drive in expressway or non-congested sections, and the air filter should be replaced in time. Finally, we must choose regular channels to buy engine oil and gasoline to avoid using inferior products to affect the use of vehicles. Million car purchase subsidy
