Why does the car shake like a convulsion when accelerating?

[DelAubree]

Car shaking like a convulsion during acceleration can be caused by the following reasons: Excessive carbon deposits inside the engine: Carbon deposits may accumulate in the fuel injectors, throttle body, intake manifold, and spark plugs, requiring thorough cleaning. Blockage in the fuel system: The fuel system needs to be cleaned, and the fuel filter should be replaced. Engine oil needs to be changed: If the engine oil has reached its replacement interval, it should be changed along with the oil filter. Below is a relevant introduction: When a car experiences shaking during acceleration in daily use, a diagnostic approach should be employed to inspect the engine system. After identifying the specific cause of the issue, repairs should be carried out. Post-repair, professional personnel will conduct a test drive to ensure the vehicle is problem-free before returning it to the owner.
