Solution

1. Preparation

Gather tools and materials needed for the repair.
Disconnect the negative terminal of the battery to prevent electrical shock.
Ensure the vehicle is parked on a flat surface and the engine is cool.

2. Clean or Replace the Throttle Body

Remove the air intake duct connected to the throttle body using a socket set.
Spray throttle body cleaner into the throttle body and use a clean cloth to wipe away carbon deposits.
Reinstall the air intake duct and ensure all clamps are tight.

3. Service the Idle Air Control Valve (IACV)

Locate the IACV on the throttle body (refer to the service manual for specific location).
Disconnect the electrical connector and remove the IACV using a socket set.
Clean the IACV with throttle body cleaner or replace it if it is faulty.
Reinstall the IACV and reconnect the electrical connector.

4. Inspect and Replace Spark Plugs (if necessary)

Remove the ignition coils using a socket set.
Extract the spark plugs using a spark plug socket.
Inspect the spark plugs for wear; replace them with OEM parts if necessary.
Reinstall the spark plugs and ignition coils, ensuring they are torqued to manufacturer specifications.

5. Check and Replace Fuel Filter (if applicable)

Locate the fuel filter (refer to the service manual for specific location).
Disconnect the fuel lines, being cautious of residual fuel.
Remove the old fuel filter and install a new one, ensuring the correct orientation.
Reconnect the fuel lines and check for leaks.
