Solution

1. Preparation

Gather tools and parts needed for repair.
Disconnect the negative battery terminal to ensure safety during repairs.
Allow the engine to cool if it has been running recently.

2. Clean/Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect it for dirt or damage.
If dirty, replace it with a new, clean air filter. Reassemble the housing cover securely.

3. Inspect and Replace Fuel Filter

Locate the fuel filter and relieve fuel system pressure by removing the fuel pump relay and running the engine until it stalls.
Disconnect fuel lines from the filter using a fuel line disconnect tool.
Remove the old fuel filter and install the new one, ensuring proper orientation (check arrows on the filter).
Reconnect fuel lines and restore fuel pump relay.

4. Clean Throttle Body

Remove the throttle body from the intake manifold after disconnecting the electrical connectors and the intake duct.
Use throttle body cleaner and a clean rag to remove carbon buildup from the throttle plate and inside the housing.
Reinstall the throttle body and connect all components securely.

5. Inspect and Replace Spark Plugs

Remove the ignition coil covers if applicable.
Use a spark plug socket to remove the old spark plugs.
Inspect for wear; replace with new spark plugs that meet manufacturer specifications (check gap settings).
Reinstall ignition coils and covers.

6. Check Exhaust System

Inspect the exhaust system visually for any signs of damage or blockage.
If the catalytic converter is suspected of being clogged, consider testing exhaust back pressure with a gauge.
Replace any damaged components or consider cleaning the catalytic converter if applicable.
