Solution

1. Preparation

Gather tools and parts required for repair.
Disconnect the negative terminal of the battery to ensure safety while working on electrical components.

2. Addressing Engine Codes

Sub-step 1: Use the OBD-II scanner to retrieve and document all error codes.
Sub-step 2: Research each code to understand possible causes and repair strategies.
Sub-step 3: Clear the codes and perform a test drive to see if they reappear.

3. Fuel System Inspection

Sub-step 1: Check fuel pressure using a fuel pressure gauge; compare readings to manufacturer specifications.
Sub-step 2: Replace the fuel filter if it shows signs of clogging or has not been replaced in accordance with maintenance schedules.
Sub-step 3: If the fuel pump is faulty, remove and replace it, ensuring all connections are secure.

4. Air Intake and Throttle Body Cleaning

Sub-step 1: Remove the air intake duct and inspect for obstructions or leaks.
Sub-step 2: Clean the throttle body using a throttle body cleaner to remove carbon buildup.
Sub-step 3: Reinstall the air intake duct securely.

5. Ignition System Check

Sub-step 1: Remove spark plugs and inspect for wear or fouling; replace if necessary.
Sub-step 2: Test ignition coils with a multimeter to ensure proper resistance; replace any faulty coils.
Sub-step 3: Reinstall new spark plugs with proper torque specifications.

6. Final Checks

Sub-step 1: Reconnect the battery and perform another OBD-II scan to verify that no new codes have appeared.
Sub-step 2: Take the vehicle for a test drive under varying conditions to check for power delivery and engine performance.
