Disconnect the battery to prevent electrical shorts.

2. Address Fault Codes

Sub-step 1: Using the OBD-II scanner, clear existing trouble codes after repairs.
Sub-step 2: Re-scan the vehicle to confirm codes are no longer present.

3. Replace Spark Plugs and Ignition Coils (if needed)

Sub-step 1: Remove engine cover (if applicable) using a ratchet and socket set.
Sub-step 2: Disconnect electrical connectors from ignition coils.
Sub-step 3: Unscrew the ignition coils and remove them.
Sub-step 4: Remove old spark plugs using a spark plug socket.
Sub-step 5: Install new spark plugs, torque to manufacturer specifications (usually around 15-20 ft-lbs).
Sub-step 6: Reinstall ignition coils and reconnect electrical connectors.

4. Inspect and Repair Air Intake System

Sub-step 1: Remove the air filter housing using a screwdriver and socket set.
Sub-step 2: Inspect the air filter for dirt or blockages and replace if necessary.
Sub-step 3: Check air intake hoses for cracks or disconnections and replace as needed.
Sub-step 4: Reassemble air intake components securely.

5. Check Fuel System

Sub-step 1: Connect a fuel pressure gauge to the fuel rail.
Sub-step 2: Turn the ignition to the ON position without starting the engine and check fuel pressure.
Sub-step 3: If pressure is low, inspect fuel pump and filter for issues and replace as necessary.
