What is the normal idle speed for a cold start?

[McCollin]

Generally, the normal idle speed for a cold start ranges between 500 and 850 RPM, while the instantaneous idle speed during a cold start can be between 1500 and 2000 RPM. Here is an introduction to car idle speed: 1. When a car engine runs without any load, it is called idling. When the accelerator pedal is fully released during engine operation, the engine enters an idle state. The engine speed during idling is referred to as the idle speed. The idle speed can be adjusted by modifying the throttle opening size, among other methods. The optimal idle speed is the lowest RPM at which the engine does not shake. 2. After a cold start, there is a high idle speed process, which is more noticeable in winter. This is a phenomenon controlled by the vehicle's onboard computer (especially in vehicles with electronic throttle control systems). Once the engine reaches a certain temperature, the idle speed will return to normal.
