How to solve the problem of high idle speed of antelope car

The reason why the idle speed of the car is too high is that the engine of the car has too much carbon deposit.

The solution is: go to the 4S shop or repair shop of the car in time, clean up the carbon deposit on the engine of the car in time, and solve the problem of high idle speed of the car. If it has not been solved, it is recommended to overhaul the engine of the car.

Generally speaking, the common reasons for the high idle speed of automobile engines are that the throttle is stuck and closed loosely; Idle speed control valve failure; Water temperature sensor failure; Air intake system leaks, air conditioning switch and power steering gear pressure switch are faulty. Carbon deposition will cause the idling control valve to jam or the throttle valve cannot be closed normally, so that the electronic control unit cannot accurately adjust the idling speed of the engine.

Extended data:

The solution to the high idle speed of automobiles is as follows:

The normal idle speed of EFI engine is determined by idle speed control valve. According to the engine speed, temperature, throttle switch, air conditioning switch and other signals, the electronic control unit will increase the intake bypass passage of the idle speed control valve or directly increase the throttle opening after calculation, thus increasing the air intake and improving the engine idle speed.

In general, the air intake must be strictly limited. If the air intake pipe leaks, the air flow sensor can't measure the real air intake, and the electronic control unit can't accurately control the air intake, which leads to the unstable idle speed of the car.

People's Network-Frequent high-speed driving can reduce carbon deposition and minimize vehicle idle speed.
