Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery cable to prevent electrical shorts.
Ensure the engine is cool before beginning work.

2. Clean or Replace Air Filter

Remove the air filter housing cover (usually requires a socket set).
Take out the air filter and inspect it.
- If dirty, clean it or replace it with a new one.
Reinstall the air filter and housing cover securely.

3. Check and Replace Fuel Filter

Locate the fuel filter (consult the service manual for exact location).
Relieve fuel pressure by removing the fuel pump fuse and running the engine until it stalls.
Disconnect the fuel lines from the filter using appropriate tools, taking care to catch any spilled fuel.
Replace the old filter with a new one, ensuring proper orientation.
Reconnect the fuel lines and reinstall the fuse.

4. Clean Throttle Body

Remove the throttle body (may require a socket set and screwdrivers).
Use throttle body cleaner and a soft cloth to clean the interior surfaces.
Ensure the throttle plate moves freely and reassemble the throttle body to the intake manifold with proper torque specifications.

5. Inspect and Replace Spark Plugs

Remove the ignition coil(s) using a socket set.
Take out the spark plugs with a spark plug socket.
Inspect for wear; replace any worn plugs with the manufacturer-recommended type.
Reinstall the spark plugs and ignition coil(s), ensuring they are properly seated.

6. Test and Clean MAF Sensor

Disconnect the MAF sensor electrical connector.
Remove the MAF sensor from its housing.
Clean the MAF sensor with MAF cleaner spray (do not touch the sensor elements).
Reinstall the MAF sensor and reconnect the electrical connector.
