Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical hazards.

2. Address Engine Codes

Using the OBD-II scanner, clear any existing codes after noting them.
If codes reappear after repairing, further investigate specific issues indicated.

3. Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and clean the housing.
Install the new air filter and secure the housing cover.

4. Fuel System Inspection

Connect a fuel pressure gauge to the fuel rail.
Start the engine and check for proper fuel pressure (consult manufacturer specifications).
If pressure is low, inspect the fuel pump and replace if necessary.

5. Inspect and Replace Spark Plugs

Remove the ignition coils using a socket set.
Take out the spark plugs using a spark plug socket.
Check the plugs for wear; replace with OEM parts as needed.
Reinstall the spark plugs and ignition coils, ensuring proper torque settings.

6. Electrical System Check

Using a multimeter, measure battery voltage; it should be around 12.6 volts.
Inspect battery terminals for corrosion and clean as necessary.
Tighten any loose connections.

7. Exhaust System Inspection

Visually inspect the exhaust system for any signs of damage or blockages.
If a clogged catalytic converter is suspected, consider performing a back-pressure test.
