What Causes Jerking When Accelerating at Low Speeds in a New Car?

[McLillian]

The reasons for jerking when accelerating at low speeds in a new car include excessive carbon buildup in the throttle body, poor fuel quality, and differences in vehicle types. Excessive carbon buildup in the throttle body: Many malfunctions are caused by carbon buildup, and some vehicles may experience jerking due to carbon deposits. It is recommended to regularly clean carbon deposits. Poor fuel quality: Poor or mismatched fuel quality can lead to incomplete combustion. Different vehicle types: In manual transmission vehicles, jerking can occur when accelerating or decelerating while the clutch is partially engaged. The deeper the throttle is pressed, the more pronounced the jerking becomes. In automatic transmission vehicles, there may be slight jerking when accelerating and upshifting, and it becomes more noticeable when forcefully downshifting and then upshifting with a heavy throttle.
