Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, fuel pressure gauge, multimeter, cleaning supplies.
Ensure the vehicle is parked on a level surface and the engine is cool before beginning work.

2. Address Error Codes

Connect the OBD-II scanner to the vehicle's port.
Record any error codes and clear them. Note down the codes for further investigation if they reappear.

3. Inspect and Clean the Throttle Body

Tools Required: Throttle body cleaner, soft cloth.
Disconnect the negative battery terminal.
Remove the intake duct connected to the throttle body.
Use throttle body cleaner to clean any carbon buildup inside the throttle body using a soft cloth.
Reassemble the intake duct and reconnect the battery terminal.

4. Replace Spark Plugs and Ignition Coils

Tools Required: Socket set, torque wrench.
Remove the engine cover if applicable.
Disconnect the ignition coils from the spark plugs.
Remove the old spark plugs using a socket wrench.
Install new spark plugs with the correct torque (typically 15 ft-lbs) as specified in the service manual.
Reinstall the ignition coils and reconnect them.

5. Check and Replace Fuel Filter

Tools Required: Socket set, fuel line removal tool.
Relieve fuel pressure by removing the fuel pump fuse and running the engine until it stalls.
Disconnect the fuel lines from the fuel filter.
Remove the old fuel filter and install a new one, ensuring it is oriented correctly.
Reconnect the fuel lines and install the fuse back into the fuse box.
