What Causes the Engine Yellow Light to Illuminate and the Car to Shake?

[OLondon]

Reasons for the engine yellow light illuminating and car shaking: 1. Poor combustion of the air-fuel mixture in the engine, resulting in an overly rich mixture in the cylinders; 2. Malfunction of spark plugs, high-voltage wires, or ignition coils; 3. Abnormal fuel supply pressure or failure of the intake pressure sensor. The car engine is the device that provides power to the vehicle, determining its power, fuel efficiency, stability, and environmental performance. Depending on the power source, engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrid systems. Common gasoline and diesel engines are both types of reciprocating piston internal combustion engines, which convert the chemical energy of fuel into the mechanical energy of piston movement to deliver power output.
