Is it okay to adjust the idle speed to 1000?

[OAustin]

Adjusting the idle speed to 1000 is not recommended. The normal idle speed range is 550-700 RPM. If the idle speed is too high, it will increase fuel consumption, cause unnecessary losses, and affect normal operation. Normal idle speed: The normal range is 700-800 RPM. If it's too low, the engine may vibrate excessively, and if it's too high, fuel consumption will increase. Design engineers generally aim for the lowest possible idle speed that avoids vibration to save fuel. Hazards of excessively high idle speed: If a car's idle speed is too high, check for loose or leaking intake manifolds, as this can significantly increase fuel costs and accelerate engine carbon buildup. If the idle speed is too low, there's a risk of stalling while driving. If the idle speed fluctuates, it could indicate faulty spark plugs or ignition coils, causing the engine pistons to malfunction and resulting in severe vibration.
