What Causes a Heavy Gas Pedal?

[SanJude]

The reasons for a heavy gas pedal are: 1. The spring under the gas pedal is too stiff; 2. The spring's elasticity is too strong; 3. The fuel filter is clogged; 4. The spark plugs are damaged; 5. There is an issue with the throttle. The gas pedal is part of the vehicle's fuel supply system, controlling the opening of the engine throttle by adjusting the amount of pedal depression, thereby regulating air intake and engine speed. The correct method to operate the gas pedal is: 1. Place the heel of the right foot on the floor of the driver's compartment as a pivot; 2. Gently press the accelerator pedal with the ball of the foot, using ankle joint flexion to press or release; 3. When releasing the gas pedal, apply force gently, ensuring a smooth and gradual lift.
