What should I do if the second-generation cold start engine of Chang 'an Star shakes for a few seconds and then shuts down?

2. Remove the carbon deposit inside the engine.

3. Replace with better fuel.

Engine jitter is serious, which may lead to flameout tendency:

1, the throttle is too dirty. Excessive carbon deposition in the throttle valve directly leads to unstable idle speed and poor acceleration of the engine.

2. Too much carbon deposition in the engine will reduce the volume of the combustion chamber, and the endothermic characteristics of carbon deposition will also lead to non-growth combustion in the combustion chamber, increase the knock probability and make the engine shake.

3. The engine stalled. The spark plug does not ignite correctly or the nozzle does not atomize, and the cylinder does not burn completely or at all.

4. The fuel is not good.

5. After the hot car is started, the car does not start directly, and the oil lubrication between engine parts is not in place.
