What Causes Jerking Sensation During Acceleration in Manual Transmission Cars?
1 Answers
Manual transmission cars may experience jerking during acceleration due to excessive carbon buildup in the throttle body, substandard fuel quality, or variations between different vehicle models. Below are detailed explanations of these causes: Excessive carbon buildup in the throttle body: Carbon deposits can cause various malfunctions, and in some vehicles, they may lead to jerking sensations. Regular carbon cleaning is recommended. Substandard fuel quality: Poor or incompatible fuel quality can result in incomplete combustion. Different vehicle models: In manual transmission vehicles, operating in a semi-clutch state while accelerating or decelerating can cause jerking sensations. The harder the accelerator is pressed, the more pronounced the jerking becomes. Automatic transmission vehicles may experience slight jerking during upshifts, with more noticeable sensations during forceful downshifting followed by upshifting.
