Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to ensure safety while working on the electrical components.

2. Inspect the Gas Pedal Assembly

Remove the floor mat and any coverings around the gas pedal.
Look for any objects or debris that may be obstructing the pedal's movement.
If no obstructions are found, proceed to the next step.

3. Check Throttle Cable/Linkage

Depending on the design, locate the throttle cable or linkage connected to the gas pedal.
Inspect for any damage, kinks, or binding in the cable. If damaged, replace it with a new throttle cable.
Ensure that the throttle linkage moves freely without resistance.

4. Clean the Throttle Body

Locate the throttle body and remove any air intake ducts connected to it.
Use throttle body cleaner and a soft cloth to remove carbon buildup from the throttle plate and surrounding area.
After cleaning, reassemble the intake ducts.

5. Test the Electronic Throttle Control (if applicable)

Reconnect the battery and turn the ignition to the "ON" position without starting the engine.
Use a diagnostic scanner to check the throttle position sensor readings.
If the readings are out of range, replace the throttle position sensor.

6. Final Assembly and Testing

Reinstall any components removed during the inspection and cleaning process.
Ensure all connections are secure.
Start the engine and test the gas pedal function to confirm it returns to the idle position.
