• Carefully lift out the old air filter.
• Install the new air filter, ensuring it is seated properly.
• Reattach the air filter housing cover and tighten the screws.

3. Clean or Replace Fuel Injectors

• Remove the engine cover (if applicable) using a socket set.
• Disconnect the fuel injector connectors and unbolt the fuel rail.
• Carefully remove the injectors; clean them with a specialized injector cleaner or replace them if necessary.
• Reinstall the injectors, ensuring proper seating and reattach the fuel rail.

4. Inspect and Repair Vacuum Leaks
