There is obvious current sound after starting. Is there something wrong with the throttle?

Hello, I suggest checking whether the throttle is dirty. After turning off the power supply, it takes electricity to reset all electrical appliances, but the current sound can't be heard. What you should hear is the noise of the motor when the throttle valve in the engine compartment is reset. Under normal circumstances, there will be a "squeak" when driving to the ON gear. If the sound lasts too long, the throttle may be dirty.
