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

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

Generally speaking, under normal circumstances, the idle speed of a car is between 600 and 850, but it is difficult to reach 600. The engine speed of most models is around 700-800 when idling. If the difference is too large, for example, the idle speed suddenly rises to 1200, it is likely that there is something wrong with an engine component.

Causes of low idle speed

1, the throttle is too dirty

In this case, it is necessary to clean the throttle.

2, idle speed control valve failure

This problem is not common. If so, the idle control valve needs to be replaced.

There is too much carbon in the cylinder.

This phenomenon is also relatively common, and the solution is to clean up the carbon deposits.

4. The fuel injector is poorly atomized or blocked.

In this case, the fuel injector should be cleaned first. If not, only the fuel injector can be replaced.

5. There are impurities in the oil circuit.

Many car owners go to some informal gas stations to refuel in order to save some money. Inferior gasoline has many impurities, some of which are mixed with water.
