Solution

1. Preparation

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

2. Replace Fuel Filter

Locate the fuel filter (usually under the vehicle or in the engine bay).
Use a wrench to loosen the clamps or fittings securing the fuel lines.
Remove the old fuel filter and install the new one in the correct orientation.
Reconnect the fuel lines and clamps securely.

3. Replace Spark Plugs

Remove the engine cover if necessary.
Disconnect the ignition coils or spark plug wires carefully.
Use a spark plug socket and ratchet to remove old spark plugs.
Inspect the gap and condition of new spark plugs, adjust gap if required.
Install new spark plugs and reconnect ignition coils or wires.

4. Clean or Replace Air Filter

Open the air filter housing as per the manufacturer's instructions.
Remove the old air filter and inspect the housing for debris.
Install a new air filter or clean the existing one if reusable.
Ensure that the air filter housing is sealed properly before closing.

5. Check and Repair Vacuum Leaks

Visually inspect vacuum hoses for cracks or disconnections.
Use a smoke machine or carburetor cleaner to detect leaks while the engine is running.
Replace any damaged vacuum lines or hoses.
