Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Air Filter

Locate the air filter housing and remove the screws or clips.
Carefully take out the old air filter and inspect it for dirt or damage.
Install a new air filter that meets manufacturer specifications.
Reassemble the air filter housing.

3. Check and Replace Fuel Filter

Locate the fuel filter in the engine bay or under the vehicle.
Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.
Disconnect fuel lines using a fuel line disconnect tool, ensuring to catch any spilled fuel.
Replace with a new fuel filter, ensuring correct orientation and tight connections.

4. Clean Throttle Body

Remove the air intake duct connected to the throttle body.
Spray throttle body cleaner onto a clean cloth and wipe the throttle body, especially around the butterfly valve.
Use a soft brush to remove any stubborn deposits.
Reassemble the intake duct securely.

5. Inspect and Replace Spark Plugs

Remove the ignition coils or spark plug wires from the spark plugs.
Using a socket set, remove the old spark plugs and inspect them for wear or fouling.
Install new spark plugs with the correct gap as specified by the manufacturer, torquing to the recommended value (usually around 13-15 lb-ft).
Reattach the ignition coils or spark plug wires.

6. Exhaust Inspection

Inspect the exhaust system visually, looking for signs of damage or blockage.
If a clogged catalytic converter is suspected, perform a back pressure test.
Replace the catalytic converter if it is confirmed to be clogged.
