Why does the accelerator pedal feel heavy when pressed?

[LaLyla]

The reasons for a heavy accelerator pedal are: 1. The power assist component is faulty; 2. There is an obstruction in the transmission part, or friction has increased; 3. The throttle body is dirty. The accelerator is generally controlled by a pedal, also known as the acceleration pedal, which is a device used to control the fuel supply of the vehicle's engine. The operation of the accelerator pedal should use the right heel placed on the floor of the driver's compartment as a pivot, with the sole gently pressing on the accelerator pedal, using the flexion and extension of the ankle joint to press down or release. When pressing or releasing the accelerator pedal, the force should be gentle, ensuring a light press and slow release. During operation, the accelerator should be increased or decreased according to road conditions and actual needs, and the selected gear should be appropriate, allowing the engine to run most of the time at medium speed and with a larger throttle opening to save fuel.
