Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, fuel pressure gauge, cleaning supplies.
Ensure the vehicle is parked on a level surface and the engine is turned off. Disconnect the battery to prevent electrical issues during inspection.

2. Scan and Analyze Codes

Use the OBD-II scanner to retrieve error codes.
Document the codes and research them to understand the underlying issues.

3. Inspect and Replace Ignition Components

Spark Plugs:
- Remove the ignition coils using a socket set.
- Inspect the spark plugs for signs of wear, such as fouling or excessive gap.
- Replace with OEM equivalent plugs if necessary, torquing to manufacturer specifications (typically around 13-15 lb-ft).
Ignition Coils:
- If any ignition coils are faulty (check codes), replace them and ensure they seat properly.

4. Check Fuel System

Fuel Pressure:
- Connect a fuel pressure gauge to the fuel rail.
- Check that fuel pressure meets manufacturer specifications (usually around 50-60 psi).
- Replace the fuel filter if pressure is low.
Fuel Injectors:
- Inspect for leaks or clogs.
- Clean injectors using a professional injector cleaning service if necessary.

5. Inspect MAF Sensor and Throttle Body

Remove the MAF sensor and clean it with MAF cleaner spray.
Inspect the throttle body for carbon buildup and clean as needed using throttle body cleaner.
Reinstall components securely.

6. Reconnect Battery and Test

Reconnect the battery terminals and start the engine.
Monitor the engine light to see if it remains off and listen for any abnormal noises.
