Will a manual transmission car move forward by itself in first gear without pressing the accelerator?

[DelRyder]

It can move without pressing the accelerator, but you must release the clutch slowly, otherwise the car may jerk and stall. Introduction to the accelerator: The accelerator, also known as the "throttle," is a control device that regulates the engine's power (thrust). In piston aircraft engines, the throttle controls the carburetor's throttle opening to adjust the cylinder's filling volume, thereby determining the engine's output power. In gas turbine engines, the throttle regulates the metered fuel flow through the fuel controller, thus determining the engine's thrust. Introduction to the accelerator pedal: The accelerator pedal, also called the gas pedal, is part of the car's fuel supply system. By controlling the amount of pedal depression, it adjusts the engine's throttle opening to regulate the air intake, while the computer controls the fuel quantity, thereby managing the engine's speed.
