What is the reason for the idling jitter of Angkor Sela?

The engine has a serious carbon deposit, and the most common reason for car jitter is that the throttle valve is too dirty or the injector has too much carbon deposit. When there is too much carbon deposit in the engine, the gasoline sprayed by the fuel injection head will be absorbed by the carbon deposit during cold start, resulting in this phenomenon.

Engine cylinder missing: Engine cylinder missing mainly refers to the abnormal operation of one or more cylinders of the engine, which is manifested by the obvious intermittent exhaust gas flow from the automobile, the severe vibration of the exhaust pipe, and the obvious feeling of engine jitter, sometimes accompanied by sudden noise. This is mostly related to ignition coil failure. The engine combustible mixture is sometimes lean and sometimes rich, which causes idling jitter after cold start. The lower the temperature, the more engine oil and carbon deposit are needed for cold start, which will affect the success of cold start.

The simplest and most common question is whether the fuel label is wrong. If the fuel grade of 92/95 gasoline applied to the engine is too low, it will cause knocking and the idle speed will obviously shake. If low-grade fuel is added by mistake or unsafe private oil is added, low octane number will lead to this problem.
