How to Adjust a Heavy Accelerator Pedal?

[LeCameron]

Methods to adjust a heavy accelerator pedal include: 1. Adjust the throttle to check for any stiffness in rotation; 2. Add some lubricant to the accelerator cable to make it smoother; 3. Inspect the car's electronic throttle and check if the pedal is stiff, and repair it promptly if necessary. Reasons for a heavy accelerator pedal include: 1. The spring under the accelerator pedal is too stiff or has excessive tension—use a tool to stretch the spring in the opposite direction to reduce its tension; 2. Dirt accumulation in the throttle causing sensor insensitivity; 3. Insufficient pressure from the fuel pump.
