Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative terminal of the battery for safety.

2. Replace Air Filter

Remove the air intake cover by unscrewing the retaining screws.
Take out the old air filter and inspect for dirt and debris.
Install a new air filter, ensuring it fits securely in place.
Reattach the air intake cover and secure it with screws.

3. Clean Throttle Body

Remove the throttle body from the intake manifold by disconnecting the electrical connector and unscrewing the mounting bolts.
Clean the throttle body using throttle body cleaner and a soft cloth, paying special attention to the throttle plate.
Reinstall the throttle body and reconnect the electrical connector.

4. Check and Replace Fuel Filter (if applicable)

Locate the fuel filter along the fuel line (if separate from the fuel pump).
Relieve fuel system pressure by loosening the fuel filler cap and disconnecting the fuel pump fuse.
Remove the old fuel filter and install a new one, ensuring correct orientation.
Reconnect the fuel pump fuse and replace the fuel filler cap.

5. Inspect and Replace Spark Plugs

Remove the ignition coil covers and disconnect the ignition coils from the spark plugs.
Use a spark plug socket to remove the old spark plugs.
Inspect the spark plugs for wear and replace them with new ones, ensuring proper gap specifications.
Reattach the ignition coils and covers.

6. Verify Exhaust System

Inspect the exhaust system visually for any signs of damage or blockages.
If the catalytic converter is suspected to be clogged, consider performing a back pressure test or replacing it if necessary.
