What causes the BMW 5 Series to jerk and hesitate during acceleration?
1 Answers
BMW 5 Series acceleration jerking and hesitation reasons are as follows: Excessive carbon buildup: Throttle body, fuel injectors, and intake tract have significant carbon deposits. Many malfunctions are caused by carbon buildup, and some vehicles may experience jerking sensations related to this issue. It is recommended to regularly clean carbon deposits. Faulty spark plugs or ignition coils: This can lead to engine misfires (cylinder deactivation). In such cases, it is necessary to visit a repair shop for inspection and timely repairs to avoid further safety hazards. Engine speed not matching current vehicle speed: This means there is a speed difference between the engine RPM and clutch plate rotation. When shifting gears and releasing the clutch, if the engine speed does not match the vehicle speed (i.e., there's a difference between engine RPM and clutch plate rotation), jerking will occur.
