Can VIOS drive when the idle speed fluctuates?

This situation may be that the total speed motor of the throttle is damaged, and the throttle should be replaced after this happens. The throttle is called the throat of the engine. The throttle valve is used to control the intake of the engine. The throttle valve will be fixed at the head of the engine intake manifold. After the driver steps on the accelerator pedal, the throttle opening will become larger, which can increase the air intake of the engine. When the accelerator pedal is released, the opening of the throttle will be smaller, so the amount of air entering the engine will also be less.

If the sensor detects an increase in the amount of air entering the engine, it will increase the fuel injection, thus increasing the engine speed. If the sensor detects a decrease in intake air, it will reduce fuel injection, so that the engine speed will decrease.
