Solution

1. Preparation

Gather tools such as a socket set, screwdriver set, and throttle body cleaner.
Ensure the vehicle is parked on a level surface and the engine is off, with the keys removed from the ignition.

2. Inspect and Clean the Accelerator Pedal Assembly

Step 1: Remove the floor mat to access the pedal.
Step 2: Inspect the pedal pivot point for dirt or debris. Clean with a rag if necessary.
Step 3: Apply a silicone-based spray lubricant to the pivot area and work the pedal to ensure smooth operation.

3. Examine the Throttle Body

Step 1: Locate the throttle body by following the air intake duct from the air filter.
Step 2: Disconnect the negative battery terminal to ensure electrical safety.
Step 3: Remove the air intake duct connected to the throttle body (usually secured with clamps).
Step 4: Inspect the throttle plate for carbon buildup. Use throttle body cleaner and a soft cloth to remove any deposits.
Step 5: Reassemble the air intake duct and reconnect the negative battery terminal.

4. Check and Adjust the Throttle Cable (if applicable)

Step 1: If the vehicle is equipped with a throttle cable, locate the cable at the throttle body.
Step 2: Inspect the cable for any fraying or binding. Replace if necessary.
Step 3: Adjust the cable tension according to the manufacturer's specifications, ensuring it is not too tight.
