Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Scan and Analyze Codes

Use the OBD-II scanner to retrieve error codes.
Document the codes and research their meanings to determine the affected systems.

3. Inspect Spark Plugs

Remove the ignition coil covers to access the spark plugs.
Use a spark plug socket to remove each spark plug.
Inspect for signs of carbon buildup, wear, or damage; replace if necessary.
Torque new spark plugs to manufacturer specifications (typically 13-15 lb-ft).

4. Check for Vacuum Leaks

Inspect hoses and gaskets in the intake system for cracks or leaks.
Use a smoke machine to detect leaks if necessary.
Replace any damaged hoses or gaskets.

5. Examine Fuel Injectors

Remove the fuel rail to access the injectors.
Clean or replace clogged injectors as needed.
Ensure proper seating of injectors upon reassembly.

6. Test Ignition Coils

Remove the ignition coils for testing.
Use a multimeter to check the resistance of each coil (reference specifications).
Replace any faulty coils.

7. Fuel System Inspection

Replace the fuel filter if it is clogged.
Check fuel pump operation and pressure (should typically be 30-60 psi).
Address any issues found with the fuel system components.
