What Causes the Jerking Sensation When Letting Off the Throttle?

[LukeLee]

Here are the reasons for the jerking sensation when letting off the throttle: Poor coordination between throttle and clutch: If the throttle and clutch are not properly coordinated during gear shifting, the vehicle may exhibit noticeable sudden deceleration followed by sudden acceleration, which is the most obvious form of 'jerking sensation.' However, in automatic transmissions, since the gear shifts are controlled by the computer, theoretically, it should be smoother. But due to the structure of the transmission, the severity of the jerking sensation varies in automatic vehicles. Fuel octane rating issue: You can perform some simple checks yourself, such as whether the wrong fuel was added. This is a possibility because using lower octane fuel may result in sluggish acceleration, leading to reduced engine power and increased fuel consumption.
