Spark 1.0 What should I do if the idle speed is high after cleaning the throttle?

SPARK 1.0L 2009, the engine is imported from Korea, and the electronic throttle body is semi-electronic.

Idle speed control is controlled by the motor that directly controls the throttle, and the throttle opening of part of the load is realized by the cable.

The system is equipped with the engine controller of Siemens Company of Korea.

After cleaning the throttle body, it is necessary to:

1, the self-learning value in the engine controller is cleared (use SCAN 100, or X43 1, preferably SCAN 100, manufactured by Daewoo, Korea).

2. Turn off all electrical appliances, such as air conditioners, lights, wipers, stereos, etc.

3. Without stepping on the accelerator, turn on the key 1 min, and then turn off the power 1 min;

4, don't step on the accelerator, after the engine starts, let it idle naturally 15 minutes, so as to complete the idle self-learning;

Without self-learning, the engine idle speed can't be controlled.

Another possibility is that when the throttle body is put back, the sealing ring is not installed properly, and the idle speed will continue to be high if air leaks in.
