Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the battery to prevent electrical shorts during work.

2. Address Fuel System Issues

a. Replace Fuel Filter
- Locate the fuel filter, usually in the fuel line under the vehicle.
- Use a socket set to remove the old fuel filter and install the new one, ensuring the orientation is correct.
b. Clean Fuel Injectors
- Use a fuel injector cleaning kit or remove injectors for manual cleaning.
- Follow the manufacturer’s instructions for cleaning or replacing injectors.

3. Throttle Body Cleaning

Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft rag to clean the throttle plate and surrounding areas.
Reinstall the air intake duct securely.

4. Ignition System Inspection

Remove the spark plugs using a spark plug socket.
Check for wear (electrode condition, gap) and replace if necessary.
Inspect ignition coils for cracks or damage, replacing any faulty components.

5. Exhaust System Check

Inspect for any visible damage or leaks in the exhaust system.
If a blockage is suspected, consider using a smoke test to identify leaks or obstructions.
Replace damaged sections or components as needed.
