Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, fuel pressure gauge, throttle body cleaner, torque wrench.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the engine to cool before starting work.

2. Address Error Codes

Sub-steps:
1. Connect the OBD-II scanner to the vehicle's diagnostic port and retrieve trouble codes.
2. Document any codes and research their meanings to guide further inspection.
3. Clear the codes and test drive the vehicle to see if they reappear.

3. Replace Air Filter

Sub-steps:
1. Locate the air filter housing and unclip or unscrew it.
2. Remove the old air filter and inspect for dirt and damage.
3. Install a new OEM air filter, ensuring it fits snugly in the housing.
4. Reassemble the housing and securely fasten it.

4. Check Fuel Pressure

Sub-steps:
1. Locate the fuel pressure test port on the fuel rail.
2. Connect the fuel pressure gauge to the port.
3. Turn the ignition to the "ON" position (do not start) and check the pressure reading; it should match the manufacturer specifications.
4. If pressure is low, consider inspecting or replacing the fuel pump.

5. Clean or Replace Throttle Body

Sub-steps:
1. Disconnect the throttle body connector and remove any intake hoses attached.
2. Remove the throttle body by unbolting it from the intake manifold.
3. Clean the throttle body with throttle body cleaner using a soft rag or brush.
4. Reinstall the throttle body and reconnect any hoses and electrical connectors.

6. Replace Spark Plugs

Sub-steps:
1. Remove the ignition coil covers if applicable to access the spark plugs.
2. Use a socket wrench to carefully remove each spark plug.
3. Inspect the plugs for wear and replace them with new, manufacturer-specified plugs.
4. Torque the new plugs to the manufacturer's specifications and reattach the ignition coils.
