Is it normal for the idle speed to always be at 1000 RPM?

[AidenRose]

Here is an introduction 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 changing the throttle opening size. Idle means the engine is "producing power without doing work". When the engine is running, if the accelerator pedal is fully released, the engine is in idle condition. 2. Causes of unstable idle speed: Direct causes refer to mechanical parts being dirty, worn, or incorrectly installed, leading to changes in cylinder power output, resulting in imbalance among cylinders and causing unstable idle speed. Indirect causes refer to abnormalities in the engine's electronic control system, causing poor combustion of the air-fuel mixture, making it difficult to balance cylinder power output and resulting in unstable idle speed.
