How to set the idle speed of electronic throttle

Unable to adjust. Each sensor provides information to the computer, and the computer sends instructions to the injector to control the injection time. The throttle screw is used for limiting, but the idle speed can be adjusted. Because that is to adjust the opening of the throttle blade, it is not recommended to adjust the screw. Generally, high-grade car computers can be deployed, and low-grade doors have screws. The method is as follows. 1. First loosen the throttle, adjust the screw to make the engine reach the lowest stable speed, and then put the screwdriver on the idle screw. 2. When the engine is about to stall, slowly loosen the idle screw with a screwdriver to make the engine rotate stably and reach high speed, and then loosen the throttle screw to reduce the engine speed from high to minimum; 3. Then unscrew the screw to increase the engine speed. Repeat this operation until the throttle opening reaches the minimum, and then suddenly close the throttle.
