What causes the jerking when accelerating at low speeds in a GL8?

[ChristopherLee]

The reasons for jerking when accelerating at low speeds in a GL8 are as follows: 1. Excessive carbon buildup in the throttle, fuel injectors, and intake manifold: Many malfunctions are caused by carbon buildup, and some vehicles may experience jerking related to carbon deposits. It is recommended to regularly clean carbon deposits. 2. Poor fuel quality: The use of substandard or incompatible fuel can lead to incomplete combustion. 3. Faulty spark plugs or ignition coils causing misfires: It is necessary to have these checked and repaired at a maintenance facility to avoid further safety hazards. Jerking when accelerating at low speeds can be a normal phenomenon under certain circumstances, with specific reasons as follows: 1. For manual transmission vehicles: When driving in a semi-clutch state, accelerating or decelerating can cause a jerking sensation, which becomes more pronounced with deeper throttle application. 2. For automatic transmission vehicles: There may be a slight jerking sensation when upshifting during acceleration, and it becomes more noticeable when forcefully downshifting and then upshifting with heavy throttle application.
