1 1, Paramera accelerates and starts shaking. Why?

The throttle 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 a large amount of carbon deposit during cold start, which will lead to the mixture being too thin and too thick during cold start, and the combustible mixture of the engine will be too thin and thick at times, resulting in idling jitter after cold start.

Check whether the fuel supply pressure of the spark plug and the high-pressure pilot pump is abnormal, otherwise the numerical error and poor operation of the intake pressure sensor will cause the body to shake. Poor ignition system and poor spark plug flashover can also lead to this fault phenomenon.
