What is the reason for the jerking and surging when accelerating at low speed in a GL8?
1 Answers
Introduction to the reasons for jerking and surging when accelerating at low speed in a GL8: Excessive carbon deposits in the throttle body, fuel injectors, and intake manifold: Many faults are caused by carbon deposits, and some vehicles may experience jerking due to carbon buildup. It is recommended to regularly clean carbon deposits. Poor fuel quality: Substandard or incompatible fuel quality leading to incomplete combustion. Faulty spark plugs, ignition coils, etc., causing cylinder misfires: It is necessary to have them inspected and repaired at a service center to avoid more safety hazards. Jerking when accelerating at low speed in a car can be a normal phenomenon under the following circumstances: For manual transmission models: When driving in a semi-clutch state, accelerating or decelerating can cause a jerking sensation, which becomes more pronounced with deeper throttle application. For automatic transmission models: There may be a slight jerking sensation when upshifting during acceleration, which becomes more noticeable when forcing a downshift and then upshifting with a heavy throttle.
