Should You Wait for Normal Idle Speed When Starting a Car?

[DavidRose]

It is recommended to wait for normal idle speed when starting a car. Here is some relevant information about car idle speed: 1. The function of car idle speed: Idle speed is an operating condition of a car, referring to the engine running in neutral gear. The engine speed during idle is called idle speed. The idle speed can be adjusted by modifying the throttle opening size, among other methods. Idle speed means the engine is "producing power without doing work." When the engine is running, if the accelerator pedal is completely released, the engine enters idle speed. 2. Causes of unstable idle speed: Direct causes refer to mechanical parts being dirty, worn, or incorrectly installed, leading to variations in individual cylinder power output, resulting in an imbalance in cylinder power and causing unstable idle speed. Indirect causes refer to abnormalities in the engine's electronic control system, leading to poor combustion of the air-fuel mixture, making it difficult to balance cylinder power and causing unstable idle speed.
