Dongfeng xiaokang k 17 idle speed is high!

If it is only slightly higher, it should be because of the low temperature and poor fluidity of lubricating oil. It is normal for the driving computer to increase the idle speed in order to prevent the flameout. If it is accompanied by irregular engine abnormal sound, it may be the cause of carbon deposition in throttle or nozzle;

When the idle speed of the engine is too high, start the engine first, and then control the throttle arm by hand to close the throttle. If the idle speed is normal at this time, it means that the throttle tension spring is too soft and should be replaced. If closing the throttle valve by hand is ineffective, check whether the throttle shaft is loose or whether the throttle valve is closed tightly. If the throttle valve is not tightly closed or the throttle shaft is loose, please repair it. If the throttle valve is normal, check whether there is slight air leakage under the throttle valve. If there is, eliminate the air leakage. If not, further adjust the idle speed until the idle speed is appropriate.
