Why Does the Car Jerk When Accelerating at Low Speeds?

[LeSimon]

The following are the main reasons why a car jerks when accelerating at low speeds: 1. Engine oil passage blockage: If the car jerks while driving, it may indicate an engine issue. The engine's ignition, air intake, and fuel injectors collectively determine fuel combustion, which is the source of the engine's power. If the air intake decreases, ignition weakens, or fuel injection reduces, the power output will be insufficient, resulting in a jerking sensation. 2. During the break-in period of a new car, slight jerking while driving is normal. This is because the vehicle's power output and component engagement are not yet at their optimal levels, and the transmission's computer has a self-learning mechanism that continuously adjusts oil pressure for gear shifting.
