Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect the housing for debris.
Install a new air filter, ensuring it is seated properly.
Reattach the air filter housing cover and secure it.

3. Inspect and Clean Throttle Body

Remove the throttle body assembly by disconnecting the electrical connectors and unbolting it from the intake manifold.
Use throttle body cleaner and a soft cloth to clean the interior surfaces of the throttle body.
Reinstall the throttle body, ensuring all gaskets are in good condition.
Reconnect electrical connectors and tighten all bolts to manufacturer specifications.

4. Check and Replace Spark Plugs

Remove the ignition coils using a socket set.
Take out the old spark plugs using a spark plug socket.
Inspect the spark plugs for wear or damage, and replace them with new ones if necessary.
Reinstall ignition coils and ensure they are securely fastened.

5. Fuel System Inspection

Check the fuel pressure using a fuel pressure gauge to ensure it meets specifications.
Inspect the fuel filter for blockages and replace it if needed.
If the fuel pump is faulty, replace it according to the manufacturer's guidelines.

6. Exhaust System Evaluation

Inspect the exhaust system visually for signs of damage or blockage.
If a clogged catalytic converter is suspected, perform a backpressure test.
Replace the catalytic converter if it fails the test.
