Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent any electrical issues.

2. Inspect and Clean the Accelerator Pedal Assembly

Remove any debris around the accelerator pedal.
Disconnect the accelerator pedal assembly from the vehicle.
Clean the pivot points and any moving parts with a suitable lubricant (e.g., silicone spray).

3. Inspect the Throttle Body

Remove the air intake duct to access the throttle body.
Inspect the throttle plate for carbon buildup; clean it using throttle body cleaner and a soft cloth.
Ensure the throttle plate moves freely without binding.

4. Examine the Throttle Cable (if applicable)

If the vehicle has a mechanical throttle cable, check for any fraying or damage.
Adjust the throttle cable tension if it is too tight or replace it if damaged.

5. Reassemble and Test
