2. Inspect the Gas Pedal Assembly

Remove the floor mat to ensure it is not obstructing the gas pedal.
Check the gas pedal for any physical damage or debris.
If the pedal is obstructed, clear any debris and ensure smooth operation.

3. Check Throttle Cable/Linkage

If equipped with a mechanical throttle cable, inspect it for fraying or damage.
Disconnect the throttle cable from the throttle body and manually operate the throttle to ensure it moves freely.
If there is resistance, replace the throttle cable.

4. Inspect Electronic Throttle Control (if applicable)

For vehicles with an electronic throttle, inspect the throttle body and connectors for dirt or corrosion.
Clean the throttle body using throttle body cleaner and a soft cloth.
Ensure the connector is secure and free from corrosion.
