Is 1000 RPM Idle Speed Normal for Cars in Summer?

[Leah]

An idle speed of 1000 RPM is within the normal range. Below is relevant information about car idle speed: 1. Function of car idle speed: Idle speed refers to an operating condition where the engine runs in neutral gear. The rotational speed during idle is called idle speed, which can be adjusted by modifying the throttle opening. Essentially, idle means the engine is "producing power without doing work." When the accelerator pedal is fully released while the engine is running, it enters idle mode. 2. Causes of unstable idle speed: Direct causes include dirty, worn, or improperly installed mechanical components leading to uneven cylinder power output, resulting in unstable idle. Indirect causes involve abnormal engine electronic control systems causing poor fuel mixture combustion, making it difficult to balance cylinder power and leading to unstable idle.
