What is the high idle speed of BYD f3?

The main reasons for BYD F3' s idle speed increase are: excessive air intake, excessive fuel injection or incorrect engine control signal, but the sudden increase in idle speed is not necessarily caused by the failure of the vehicle. Specific inspection and maintenance should be carried out in time to find out the symptoms. The following are the reasons for abnormal idle speed: 1. Throttle fault: Too dirty throttle will cause throttle opening error and throttle sensitivity will decrease. When idling, it may be closed improperly, resulting in abnormal idling. In addition, the throttle failure will also affect the engine's power, acceleration performance and fuel consumption, and even lead to difficulties in starting in serious cases. 2. Idle speed control valve failure: Idle speed cannot be adjusted correctly due to idle speed valve failure, which leads to serious problems such as unstable idle speed, difficult cold start, and even flameout when the throttle is released without idle speed. 3. Sensor failure: A sensor failure will make the computer misjudge or the computer itself fail, and the engine will be abnormal when idling.
