Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent electrical shock.

2. Address Ignition System Issues

Sub-step 1: Remove the engine cover (if applicable) using a socket set.
Sub-step 2: Inspect and replace spark plugs if they show signs of wear or damage. Use a torque wrench to install new plugs to the manufacturer's specified torque (typically around 15-20 lb-ft).
Sub-step 3: Check ignition coils for continuity using a multimeter. Replace any faulty coils.

3. Inspect Fuel Delivery System

Sub-step 1: Check the fuel pump operation by listening for the pump when turning the ignition to the ON position.
Sub-step 2: Connect a fuel pressure gauge to the fuel rail and verify that fuel pressure is within specifications (usually around 40-60 psi).
Sub-step 3: Replace the fuel filter if it is clogged or has not been replaced per the maintenance schedule.

4. Verify Air Intake and Exhaust Systems

Sub-step 1: Inspect the air filter and replace if it is dirty or clogged.
Sub-step 2: Check for vacuum leaks in hoses connected to the intake manifold.
Sub-step 3: Inspect the exhaust system for any obstructions or damage that could affect back pressure.

5. Clear Codes and Test Drive

Sub-step 1: Use the OBD-II scanner to clear error codes after repairs are completed.
Sub-step 2: Reconnect the battery and start the engine, allowing it to idle.
Sub-step 3: Take the vehicle for a test drive to ensure the issue is resolved and the check engine light does not reappear.
