Why is the accelerator pedal of the Lingpai a bit heavy?

[EzraAnn]

The reasons for the heavy accelerator pedal of the Lingpai are as follows: 1. The spring under the accelerator pedal is too stiff or has excessive elasticity. 2. A dirty throttle body causes inaccurate readings from the oxygen sensor. 3. Abnormal fuel pump pressure or insufficient fuel affecting fuel delivery. Methods to adjust a heavy accelerator pedal include: 1. Check if the throttle body rotates smoothly without sticking. 2. If it doesn't stick, lubricate the accelerator cable. 3. For electronic throttle systems, inspect the pedal for any sticking points. 4. If none of the above resolves the issue, consult a professional for further inspection.
