Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Address Faulty Spark Plugs and Ignition Coils

Remove the engine cover (if applicable) using a socket set.
Disconnect the wiring harness from the ignition coils.
Remove the ignition coils using a socket wrench.
Replace faulty spark plugs with new, manufacturer-recommended plugs.
Install new ignition coils, ensuring they are seated properly. Torque to the manufacturer’s specifications (typically around 15 Nm).
Reconnect the wiring harness to the ignition coils.

3. Inspect and Replace Fuel System Components

Locate the fuel filter; disconnect the fuel lines (use safety goggles and gloves).
Replace the fuel filter with a new one, ensuring proper orientation.
Clean or replace fuel injectors as necessary; use a fuel injector cleaner if looking to clean them without replacement.

4. Check Air Intake and Vacuum Lines

Inspect the air filter; replace if dirty or clogged.
Check the air intake hose for cracks or loose connections. Replace if damaged.
Inspect vacuum lines for cracks or leaks; replace any damaged hoses.

5. Reassemble and Reconnect Battery

Reattach any components removed for access.
Reconnect the battery terminals, ensuring a tight connection.
