What should I do if the idle speed is high after cleaning the electronic throttle?

Solution of high idle speed after cleaning the electronic throttle: 1, the high-speed car can be adjusted and matched by computer, and the low-speed car has screws on the door: first unscrew the throttle, adjust the screws 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 run stably and reach high speed, and then loosen the throttle screw to minimize the engine speed from high speed; 3. Then unscrew the screw to increase the engine speed, and so on until the throttle opening is minimum, and suddenly close the throttle.
