Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Replace Air Filter

Remove the air filter housing by unscrewing the mounting bolts.
Take out the old air filter and inspect the housing for debris.
Install the new air filter, ensuring it fits snugly.
Reassemble the air filter housing and secure with bolts.

3. Replace Spark Plugs

Remove the ignition coil cover, if applicable, to access the spark plugs.
Disconnect the electrical connectors from the ignition coils.
Unscrew and remove the old spark plugs using a spark plug socket.
Install new spark plugs by hand-tightening, then torque to manufacturer specifications (usually around 13-15 lb-ft).
Reconnect the ignition coils and cover.

4. Clean Throttle Body

Disconnect the throttle body electrical connector and intake duct.
Remove the throttle body from the intake manifold.
Spray throttle body cleaner on a clean cloth and wipe the interior surfaces, removing carbon deposits.
Reinstall the throttle body and reconnect the intake duct and electrical connector.

5. Check and Replace Fuel Filter (if applicable)

Locate the fuel filter, which may be in the fuel line or integrated with the fuel pump.
Relieve fuel system pressure using the fuel pump relay or fuse.
Disconnect the fuel lines and remove the old filter.
Install the new fuel filter, ensuring the flow direction matches the markings on the filter.
Reconnect the fuel lines securely.
