Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and the engine is off.
• Disconnect the battery to avoid electrical shorts.

2. Clean or Replace the Throttle Body

• Tools Required: Socket set, cleaning spray (Throttle body cleaner), rags
• Remove the air intake duct to access the throttle body.
• Use throttle body cleaner and a rag to clean the throttle body thoroughly.
• Inspect the throttle plate for free movement; ensure there are no obstructions.
• Reinstall the air intake duct securely.

3. Inspect and Clean the Idle Air Control Valve (IAC)

• Tools Required: Socket set, cleaning spray
• Locate the IAC valve; it is usually mounted on or near the throttle body.
• Disconnect the electrical connector and remove the IAC valve.
• Clean the valve with appropriate cleaning spray and a rag.
• Reinstall the IAC valve and reconnect the electrical connector.

4. Check and Replace Spark Plugs

• Tools Required: Spark plug socket, torque wrench
• Remove the engine cover if necessary to access the spark plugs.
• Using a spark plug socket, remove the old spark plugs.
• Inspect the old spark plugs for wear or carbon buildup.
• Install new spark plugs, ensuring they are gapped correctly and torqued to manufacturer specifications.
