Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shock.
Ensure the vehicle is parked on a flat surface and engage the parking brake.

2. Inspect and Clean Throttle Body

Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
Reattach the air intake duct securely.

3. Check and Replace Fuel Filter (if needed)

Locate the fuel filter (typically under the vehicle along the fuel line).
Release fuel pressure by loosening the fuel cap and then disconnecting the fuel line from the filter.
Replace the old fuel filter with a new one, ensuring the flow direction is correct.
Reconnect the fuel line and check for leaks.

4. Inspect and Replace Spark Plugs

Remove the ignition coil cover (if applicable).
Disconnect the ignition coils and remove them from the spark plug wells.
Use a spark plug socket to remove the old spark plugs.
Inspect the spark plugs for wear and replace them with new ones if necessary.
Reinstall the ignition coils and cover.

5. Test and Clean Idle Air Control Valve

Locate the IAC valve, typically mounted on or near the throttle body.
Disconnect the electrical connector and remove the valve from its housing.
Clean any carbon buildup using an appropriate cleaner.
Reinstall the IAC valve and reconnect the electrical connector.
