Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety during repairs.
Allow the engine to cool before starting work.

2. Check and Replace Air Filter

Remove the air filter housing cover using a screwdriver or socket set.
Take out the old air filter and inspect it for dirt or blockages.
Install a new air filter, ensuring it fits snugly in the housing.
Reattach the air filter housing cover and secure it.

3. Fuel System Inspection

Connect a fuel pressure gauge to the fuel rail test port.
Turn the ignition to the "ON" position (do not start the engine) and check the pressure reading against specifications (should be approximately 55-65 psi).
If pressure is low, replace the fuel filter and inspect or replace the fuel pump if needed.

4. Ignition System Maintenance

Remove the spark plugs using a socket wrench.
Inspect each spark plug for wear, carbon deposits, or damage; replace if necessary.
Check the ignition coils for cracks or corrosion and replace any faulty components.

5. Throttle Body Cleaning

Disconnect the throttle body connector.
Remove the throttle body using a socket set and carefully detach any attached hoses.
Clean the throttle body with throttle body cleaner and a soft cloth, focusing on the butterfly valve.
Reinstall the throttle body, reconnect hoses and electrical connectors.
