What Causes Jerking When Pressing the Accelerator in a Manual Transmission?

Reasons for jerking when pressing the accelerator in a manual transmission: 1. Excessive carbon buildup in the throttle body, fuel injectors, or intake manifold; 2. Poor fuel quality leading to incomplete combustion; 3. Faulty spark plugs or ignition coils causing cylinder misfires. It is necessary to have the vehicle inspected and repaired at a professional shop to avoid potential safety hazards. A manual transmission requires the driver to manually shift gears by moving the gear lever to change the gear engagement inside the transmission, altering the gear ratio to achieve speed variation. The working principle of a manual transmission involves using the shift fork to change the gear ratio of the engaged gears, thereby modifying the driving torque to suit different operating conditions.
