Why does the car engine shake and stall when starting?

[DeTucker]

The reasons for the car engine shaking and stalling when starting are: 1. Dirty throttle valve; 2. Faulty spark plug; 3. Engine cylinder not working; 4. Aging rubber components inside the engine mount and transmission mount. The car engine is the device that provides power to the vehicle, determining its power, fuel economy, stability, and environmental friendliness. Car engines are divided into diesel engines, gasoline engines, electric vehicle motors, and hybrid motors. Among them, gasoline engines and diesel engines are both reciprocating piston internal combustion engines, converting the chemical energy of fuel into the mechanical energy of piston motion to output power externally.
