Reconnect the air intake duct securely.

3. Test and Replace Fuel Pump (if necessary)

Testing:
- Connect a fuel pressure gauge to the fuel rail test port.
- Turn the ignition to the "On" position (do not start) and check the pressure reading.
Replacement:
- If fuel pressure is below specifications, relieve fuel system pressure, disconnect the battery, and remove the fuel tank.
- Replace the fuel pump and reassemble in reverse order.

4. Inspect and Replace Spark Plugs and Ignition Coils

Remove the engine cover if applicable.
Disconnect the electrical connectors from the ignition coils.
Remove the ignition coils and spark plugs using a socket set.
Replace with new spark plugs and ignition coils as per manufacturer specifications.
Reassemble the components, ensuring all connections are secure.
