How to Solve the Problem of Lower Car Idle Speed Than Before?

[DiCollin]

To address the issue of lower car idle speed than before, the solution involves cleaning the throttle body and also cleaning the air filter. When the engine is running without load, it is referred to as idling. When the accelerator pedal is fully released while the engine is running, the engine enters the idle state. The idle speed can be adjusted by modifying the throttle opening size, among other methods. Generally, the optimal idle speed is the lowest RPM at which the engine does not vibrate. Idling is necessary to overcome the engine's internal resistance and maintain a low RPM, providing convenience for drivers in various driving conditions and temporary stops, such as waiting at traffic lights or in congested traffic. Although the duration may be brief, temporarily turning off the engine can significantly improve fuel efficiency and reduce emissions.
