Is it normal for the car to idle at 600 to 700?

It is normal for the car to idle between 600 and 700.

Under normal circumstances, the idle speed of a car is between 600 and 850, and it is difficult to reach 600. The engine speed of most models is around 700-800 when idling. If the difference is too big, it is likely that there is something wrong with an engine component.

Reasons for low engine idle speed:

The valve is too dirty, in which case the throttle valve needs to be cleaned; Idle speed control valve is faulty. This problem is not common. If this is the problem, the idle speed control valve needs to be replaced. Excessive carbon deposition in cylinders is also common, and the solution is to clean up the carbon deposition. The fuel injector is poorly atomized or blocked. Replace the fuel injector.

Idle speed can be adjusted, usually by adjusting throttle opening and idling fuel supply. The idle speed of a car refers to a working condition. When the engine is idling, it is called idling, that is, the gear of the car is neutral. The engine speed at idle speed is called idle speed. Idle speed can be adjusted by adjusting the size of air door.
