Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a stable surface and is in park.
Disconnect the battery to avoid electrical shorts during repairs.

2. Address Fault Codes

Connect the OBD-II scanner and retrieve codes.
If codes indicate specific components (e.g., MAF sensor, O2 sensor), proceed to replace those components.

3. Clean or Replace Air Filter

Remove the air filter housing cover using a socket set.
Inspect the air filter; if dirty, replace it with a new one.
Ensure the housing and intake path are clear of debris.

4. Check and Replace Fuel Filter

Locate the fuel filter along the fuel line.
Relieve fuel pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect fuel lines carefully and replace the fuel filter.
Reconnect the fuel lines and fuse.

5. Clean Throttle Body

Remove the throttle body using a socket set.
Use throttle body cleaner and a soft brush to clean the interior surfaces.
Reinstall the throttle body and reconnect all electrical connectors.

6. Inspect and Replace Spark Plugs (if necessary)

Remove the ignition coil cover using a socket set.
Take out the ignition coils and inspect spark plugs for wear.
Replace spark plugs with new ones if necessary, ensuring the correct gap.
Reinstall coils and cover.
