Solution

1. Preparation

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

2. Inspect and Replace Ignition Components

Spark Plug Inspection:
- Remove spark plug wires or coils using a socket set.
- Inspect spark plugs for wear, fouling, or damage.
- Replace any faulty spark plugs with OEM parts (Torque: 13 lb-ft).
Ignition Coil Inspection:
- Remove ignition coils from the spark plugs.
- Test each coil with a multimeter for resistance (specifications in service manual).
- Replace any defective ignition coils.

3. Check for Vacuum Leaks

Visual Inspection:
- Inspect all vacuum hoses and gaskets visually for cracks or disconnections.
Smoke Test (if necessary):
- Use a smoke machine to detect leaks in the intake system.
- Repair or replace any damaged hoses or gaskets.

4. Fuel Injector Testing

Fuel Injector Inspection:
- Remove the fuel rail (ensure to relieve fuel pressure first).
- Use a fuel pressure gauge to check the fuel delivery pressure.
- Clean or replace any clogged fuel injectors.

5. Clear Codes and Test Drive

Reconnect the battery and clear all stored codes using the OBD-II scanner.
Start the engine and perform a test drive to ensure the check engine light does not return.
