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

2. Inspect and Clean the Gas Pedal Assembly

Remove any floor mats or obstructions from around the gas pedal.
Visually inspect the pedal linkage for any damage or binding points.
Clean the pedal mechanism using a suitable cleaner to remove any debris or grease buildup.

3. Check the Throttle Cable/Drive-by-Wire System

For a traditional throttle cable:
- Disconnect the throttle cable from the pedal and throttle body.
- Inspect for fraying, kinks, or binding; replace if necessary.
For a drive-by-wire system:
- Inspect the electrical connections and wiring for corrosion or damage.
- Ensure the pedal position sensor is functioning correctly.

4. Clean the Throttle Body

Remove the air intake duct to access the throttle body.
Use a throttle body cleaner and a soft cloth to clean the interior surfaces.
Ensure the throttle plate operates smoothly without sticking.

5. Reassemble and Test
