What Causes Car Vibration After Starting?

[McTucker]

The reasons for car vibration after starting are: 1. Dirty throttle body or excessive carbon buildup on fuel injectors causing shaking; 2. Worn engine mounts can also lead to vibration; 3. Low cylinder compression pressure; 4. Untimely replacement of spark plugs; 5. Engine shaking due to low fuel pressure; 6. Open circuit in high-voltage wires; 7. Dirty or clogged air filter not replaced in time. The principle of car starting is to transition the engine from a stationary state to an operational state by using external force to rotate the engine's crankshaft, initiating the internal combustion engine, igniting the combustible gas in the cylinders, and starting the working cycle. The crankshaft begins to rotate under external force until the engine runs.
