After Fiat washed the throttle, the idle speed became higher. What happened?

It may be that the idle speed is not initialized, but it will automatically match if it runs too much.

Idle state refers to the working state when the engine is idling. When the engine is running, if the accelerator pedal is completely released, the engine will be at idle speed. When adjusting the idle speed, the speed should not be high and low, otherwise it will cause early wear and tear to the engine, so it is best to adjust it in the automobile maintenance department.

Idle speed means that the engine runs with no load, and it only needs to overcome the friction resistance of its internal parts and does not output power to the outside. The lowest speed to maintain the stable operation of the engine is called idle speed, which is one of the five basic working conditions of the engine. The idle speed of an engine with good working performance is generally 550-800 rpm.

Idle speed can be adjusted by adjusting throttle opening and idling oil supply. Generally speaking, the minimum idle speed is the best when the engine does not shake in the idle speed range and the acceleration performance is good.
