Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on the fuel system.
Allow the engine to cool before commencing work.

2. Inspect and Replace Fuel Filter

Locate the fuel filter (refer to vehicle manual for exact location).
Use a wrench to disconnect the fuel lines (be cautious as fuel may spill).
Remove the old fuel filter and replace it with a new one, ensuring proper orientation.
Reconnect the fuel lines and check for leaks.

3. Clean or Replace Fuel Injectors

If fuel injectors are dirty, use a fuel injector cleaning kit or remove them for cleaning.
Follow the instructions on the cleaning kit or use a specialized ultrasonic cleaner if removed.
If injectors are damaged, replace them with OEM parts.

4. Test and Replace Spark Plugs

Remove the spark plug wires.
Use a spark plug socket to remove the old spark plugs.
Inspect for wear or fouling; replace them with the manufacturer-recommended spark plugs if necessary.
Reinstall spark plugs and reconnect the wires securely.
