Solution

1. Preparation

Gather tools and parts.
Disconnect the negative battery terminal to ensure safety.
Allow the engine to cool before proceeding.

2. Address Error Codes

Using the OBD-II scanner, document any error codes.
Clear the codes and perform a test drive to see if the codes reappear.

3. Inspect and Replace Spark Plugs

Remove the ignition coils using a socket set.
Extract the spark plugs with a spark plug socket.
Inspect the plugs for wear; replace if necessary with new ones (refer to manufacturer's specifications for type and gap).
Reinstall ignition coils and secure them with the appropriate torque (typically around 10-15 ft-lbs).

4. Test and Clean Fuel System

Attach a fuel pressure gauge to the fuel rail.
Start the engine and monitor fuel pressure; it should meet manufacturer specifications (typically around 40-60 psi).
If pressure is low, consider replacing the fuel filter and inspecting the fuel pump.
Use a fuel system cleaner additive to help clean injectors if needed.

5. Inspect Air Intake and Vacuum Lines

Remove the air intake duct to access the throttle body.
Clean the throttle body using throttle body cleaner and a soft cloth.
Check all vacuum lines for cracks or disconnections; replace any damaged hoses.

6. Reassemble and Reconnect

Reinstall the air intake duct and secure all components.
Reconnect the negative battery terminal.
Ensure all tools are removed from the engine bay.
