What Causes Jerking When Accelerating or Decelerating?

[FinleyDella]

Manual transmission jerking when releasing the throttle can be caused by transmission gear programming settings, transmission cooling issues, and other faults. Additional information is as follows: 1. Introduction: The throttle, also known as the "accelerator" or "butterfly valve," refers to the control device that regulates engine power (thrust). In piston aircraft engines, the throttle controls the carburetor's butterfly valve opening to regulate cylinder filling, thereby determining engine output. 2. Overview: The throttle pedal, or accelerator pedal, is part of the vehicle's fuel supply system. By controlling its depression amount, it regulates the engine throttle valve opening, controls air intake, allows the computer to manage fuel injection, and ultimately governs engine speed.
