Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, multimeter, fuel pressure gauge, torque wrench.
Disconnect the battery to prevent electrical shorts while working on the vehicle.

2. Address Fault Codes

Connect the OBD-II scanner to retrieve and document error codes.
Clear the codes and take the vehicle for a test drive to see if they return.
Investigate and resolve the issues indicated by any persistent codes (e.g., replace faulty sensors).

3. Inspect and Clean Air Intake System

Remove the air intake duct and inspect for blockages or damage.
Clean the air filter or replace it if necessary.
Reassemble the air intake components securely.

4. Fuel System Examination

Use the fuel pressure gauge to check for proper fuel pressure (refer to manufacturer's specifications).
If pressure is low, inspect the fuel pump, filter, and injectors for faults.
Replace any defective components found during the inspection.

5. Inspect Ignition System

Remove spark plugs and check for wear or fouling.
Replace spark plugs if they are worn beyond the manufacturer's specifications.
Test ignition coils for proper operation using a multimeter.

6. Reconnect Battery and Final Checks

Reconnect the battery terminals securely.
Start the engine and monitor for any abnormal noises or issues.
Ensure the check engine light remains off during operation.
