Does BYD l3 need to cut off the power supply before cleaning the throttle?

Hello, it doesn't matter whether the electronic throttle is suggested to be powered off or after cleaning, and it doesn't matter whether the throttle opening is controlled by wire. Just after cleaning the throttle, there will be two situations, one is that it is slightly difficult to start, and the other is that the idle speed is high after starting. These two phenomena are normal and should be eliminated as long as they are opened several times. BYD L3, as I remember, is wired, and has an idle valve alone. If it is unstable, the idle speed is high or there is no idle speed, it is generally the fault of the idle valve, and most of them cannot be cleaned. The price of replacing idle motors ranges from 35 yuan to 180 yuan. In addition, it is recommended that the air inlet of your car be maintained and cleaned without disassembly, so as to avoid possible accidental damage caused by disassembly. I hope my answer is helpful to you.
