Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Clean the Accelerator Pedal Assembly

Remove the floor mat for clear access.
Inspect the pedal for any debris or foreign objects that may cause obstruction.
If dirty, use a soft cloth and a mild cleaner to wipe down the surface of the pedal.

3. Check the Throttle Cable (if equipped)

Locate the throttle cable connection to the accelerator pedal.
Disconnect the throttle cable from the pedal and check for binding or fraying.
If damaged, replace the throttle cable with a new one.

4. Lubricate Pivot Points

Identify the pivot points of the accelerator pedal assembly.
Use a silicone-based lubricant spray to lubricate these points.
Ensure that excess lubricant does not drip onto floor mats or the accelerator mechanism.

5. Inspect the Throttle Body

Remove the air intake duct to access the throttle body.
Inspect the throttle plate for carbon buildup and clean using throttle body cleaner and a soft brush.
Reassemble the intake duct securely.
