What are the symptoms of a slight malfunction in the idle motor?

[DelRowan]

Idle motor slight malfunction symptoms include unstable idle speed, engine stalling at too low idle speed, and slow acceleration with poor performance. Relevant information about the idle motor is as follows: Introduction: The idle motor is a component that controls the idle speed of motor vehicles. When the engine is running without load, it is referred to as idling. During idling, the cross-sectional area of the idle air passage is adjusted based on the engine temperature and load to ensure optimal idle speed under various conditions. Function: The idle motor is primarily responsible for maintaining the car's idle speed, aiming to adjust the idle according to the engine load during idling. The idle stepper motor is mounted on the throttle body and controlled by the engine control unit to manage the engine idle speed. When the engine speed deviates from the idle speed, the throttle valve regulates the amount of air entering the intake manifold, which is mechanically operated by the accelerator pedal cable.
