What Causes Abnormal Noise and Inability to Increase Speed When Accelerating?

[StJayla]

Abnormal noise and inability to increase speed when accelerating may be due to low engine torque or transmission slippage and wear. Below is relevant information about the accelerator: 1. Brief Introduction: The accelerator pedal, also known as the throttle pedal, is part of the vehicle's fuel supply system. By controlling the pedal's depression, it regulates the engine throttle opening, air intake, and computer-controlled fuel injection, thereby managing the engine's speed. 2. Handling Procedure: If encountering accelerator pedal issues during the break-in period of a new vehicle, remain calm. Follow professional advice (indeed, this is the only reasonable approach)—fully depress the brake pedal to bring the vehicle to a complete stop, turn off the engine, and then contact for assistance.
