Why does the car shake for about 10 seconds during cold start and then return to normal?

[GabrielaRose]

The reason why the car shakes for about 10 seconds during cold start and then returns to normal is: carbon deposits on the throttle, weak ignition, low cylinder pressure, unqualified fuel, etc. The throttle is a controllable valve that controls the air entering the engine. There are two types: traditional cable-type and electronic throttle. After the gas enters the intake pipe, it will mix with gasoline to form a combustible mixture, which then burns to do work. There are two types of throttle: traditional cable-type and electronic throttle. The traditional engine throttle control mechanism works through a cable (soft steel wire) or a rod, with one end connected to the accelerator pedal and the other end connected to the throttle linkage plate. The electronic throttle mainly uses the throttle position sensor to control the opening angle of the throttle according to the energy required by the engine, thereby regulating the amount of air intake.
