If the idle speed is unstable, just change the throttle.

The concrete solution to the unstable idle speed of throttle when Wuling car crashes;

1 and "new idling motor", use the computer detector to clear the data of the driving computer and check whether it has been restored;

2. If the data is cleared and recovered. Please clean the throttle body assembly with cleaning agent.

3. If it doesn't work after cleaning. Please replace the throttle body assembly (including idle motor). Please choose regular accessories. After replacing the components, please clear and restore the data.

There are many reasons for engine idling instability. Generally, there are the following reasons: the dirty throttle causes the throttle to open too much, which leads to the unstable idle speed when the vehicle just takes a taxi. The problem of spark plug or ignition coil is the ignition problem, and the problem in this respect will generally be the lack of cylinder. This is idle instability. Moreover, when driving, there is insufficient power and air leakage in the intake pipe, so there is generally insufficient power and air leakage pressure in the intake pipe and exhaust pipe. Generally, the oil pump does not work, and the oil nozzle is blocked, resulting in poor oil injection.
