What should Wuling Light do if its idle speed is high?

1. Adjust or replace the throttle position sensor;

2. Clean or replace the idle speed control valve, and use a special decoder to basically set the idle speed;

3. Find the leakage point, seal it or replace relevant parts;

4. Check the timing mark and readjust the valve timing according to the standard;

5. Clean and check the fuel injection quantity of each injector to confirm that there is no blockage or leakage;

6. Replace the three-way catalytic converter;

7. Remove the carbon deposit on the EGR valve or replace the EGR valve.

Extended data:

When the vehicle is idling, the body shakes, when the vehicle is accelerating, the speed is not fast, and the fuel consumption suddenly increases. If this happens to the vehicle, it means that the engine has more carbon deposits and needs to be cleaned. Minimizing vehicle idling and high-speed driving can reduce and prevent carbon deposition.

It is reported that the pistons of the engine are out of sync. When the vehicle is turned off, the intake valves of each cylinder of the engine cannot be closed at the same time, and the gasoline sprayed in this working cycle cannot be recovered in time. Some unburned fuel will continue to be evaporated and oxidized, resulting in some soft black carbon deposits in the intake pipe, especially behind the throttle.

When the valve forms carbon deposit, a part of the fuel injected into the cylinder will be adsorbed every time, which makes the concentration of the mixture that really enters the cylinder dilute, resulting in poor engine operation, and abnormal phenomena such as body shaking at idle speed, slow speed increase of the vehicle during acceleration, and sudden increase of fuel consumption.
