The car is idling and getting taller.

The reasons for the increase in idle speed during driving are as follows:

1. Air intake sensor problem: It may be that the air intake sensor is damaged. Excessive air intake of the vehicle will increase the fuel combustion efficiency of the vehicle, and the idle speed of the vehicle will naturally increase, so the sensor should be replaced;

2. Water temperature sensor problem: If the water temperature sensor of the vehicle is damaged, the driving computer will judge whether the current water temperature of the vehicle is appropriate. If the water temperature is not suitable, the water temperature of the vehicle itself will start to increase actively. The way to improve the idle speed of vehicles is to go to a professional repair shop to clean or replace the water temperature sensor.

3. Throttle fault: The throttle position sensor of the vehicle is damaged. The vehicle thinks that the throttle is in a half-open state, but in fact the intake valve is in a full-open state. It can be solved by cleaning the throttle or replacing the throttle. Million car purchase subsidy
