Tools Required: Socket set, torque wrench.
Safety Warnings: Ensure the vehicle is secure on jack stands before working underneath it.

4. Inspect and Repair Throttle Linkage

Sub-steps:
- Open the hood and locate the throttle body and linkage.
- Check for any loose or damaged connections; adjust or replace as necessary.
- Ensure the throttle cable moves freely and returns to the closed position without sticking.
Tools Required: Screwdrivers, pliers.
Safety Warnings: Disconnect the battery before working on electrical components.

5. Reconnect Battery and Test Drive

Sub-steps:
- Reconnect the battery terminals securely.
- Start the vehicle and allow it to warm up.
