How to improve the idle speed when the idle speed of electronic throttle is low?

Generally, high-gear cars can be deployed by computer, and low-gear doors have screws. The adjustment method is as follows: 1. First unscrew the throttle adjusting 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 unscrew the idle screw with a screwdriver to make the engine run stably and reach high speed, and then unscrew the throttle screw to minimize the engine speed from high speed; 3. Then unscrew the screw and increase the engine speed repeatedly until the throttle opening is minimum, and suddenly close the throttle; 4, the above throttle adjustment idle speed will cause early engine wear. It is not recommended for car owners to adjust themselves. You'd better go to the auto repair shop to adjust it.
