How to Adjust High Car Idle Speed?

[McAthena]

Open the front hood of the car engine, locate the carburetor, and adjust the idle screw of the carburetor to increase the idle speed. Below is relevant information about car idle speed: 1. Introduction: 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. Idle speed can be adjusted by modifying the throttle size, etc. 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 is in idle condition. 2. Instability: Direct causes refer to mechanical parts being dirty, worn, or incorrectly installed, leading to changes in cylinder power, resulting in an imbalance of power among cylinders and causing unstable idle speed in the engine; 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 the power among cylinders and causing unstable idle speed in the engine.
