Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, fuel pressure gauge, screwdriver set, torque wrench.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Addressing Error Codes

Reconnect the battery and use the OBD-II scanner to read error codes.
Document any codes present; clear the codes and perform a test drive to determine if they return.

3. Inspect and Replace Fuel Filter

Tools Required: Socket set, pliers.
Locate the fuel filter, usually situated along the fuel line.
Disconnect the fuel lines using pliers and release any pressure by pressing the Schrader valve.
Remove the old filter and install the new filter in the correct orientation.
Reconnect the fuel lines and check for leaks.

4. Clean the Throttle Body

Tools Required: Screwdriver set, throttle body cleaner, clean cloth.
Remove the air intake duct connected to the throttle body.
Use the throttle body cleaner and a clean cloth to remove carbon buildup inside the throttle body.
Reassemble the air intake duct securely.

5. Replace the Air Filter

Tools Required: None (usually hand-tightened).
Locate the air filter housing, unclip or unscrew it as necessary.
Remove the old air filter and install the new one, ensuring it's seated properly.
Close the air filter housing securely.

6. Test and Replace Spark Plugs (if necessary)

Tools Required: Socket set.
Remove the ignition coil or spark plug wires and take out the spark plugs.
Inspect the spark plugs for wear or fouling; replace with OEM-specific plugs as needed.
Reinstall everything securely.
