What is the high idle speed of Baojun 730 after washing the throttle?

The reasons for the high idle speed of Pacific Auto Network Baojun 730 after cleaning the throttle are as follows: 1, the throttle valve is faulty and dirty, which will lead to the wrong throttle opening, the throttle valve sensitivity will be reduced, and the throttle valve may be closed abnormally at idle speed, resulting in abnormal idle speed; 2. Failure of the idle speed control valve will make the idle speed unable to be adjusted correctly, resulting in unstable idle speed and difficult cold start. 3, sensor failure, will make the computer judgment error, the engine idle speed will be abnormal.

When the idle speed of Baojun 730 engine is too high, start the engine first, and then control the throttle arm to close the throttle by hand. 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.

When adjusting idle speed, it must be carried out under normal conditions such as normal engine temperature, proper valve clearance, normal ignition system, good sealing of all pipelines, full throttle opening and tight throttle closing. When adjusting, first loosen the throttle opening adjustment screw to make the engine reach the lowest stable speed. Screw in the idle speed adjusting screw with a screwdriver, so that when the engine is about to turn off, screw it out slowly to make it run smoothly and reach high speed, and then screw out the throttle opening adjusting screw to minimize the engine speed. Then adjust the idle adjustment screw to increase the engine speed. Repeat this process until the throttle opening is minimum (close) and the engine is running at the lowest stable speed. Finally, increase the speed and suddenly close the throttle, so that the engine can still turn without stalling.
