Baojun 730 cleans the throttle, idling 1200 rpm.

After the throttle valve is cleaned, the idle speed is high, so it is good to use the computer to match and reset it.

The reasons for unstable idle speed and body shake are:

1. There is a lot of carbon in the engine, which leads to the change of compression ratio.

2. Idle switch is not turned off.

3. Idle speed control valve is faulty.

4. Air inlet pipe leaks.

5. The fuel injector leaks or leaks.
