Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative terminal of the battery to prevent electrical shorts.
Allow the engine to cool before performing any work.

2. Replace Air Filter

Open the hood and locate the air filter housing.
Remove the clips or screws holding the housing in place.
Carefully remove the old air filter and clean the housing interior.
Install the new air filter, ensuring it fits snugly.
Reassemble the housing and secure it with clips or screws.

3. Check and Replace Fuel Filter (if necessary)

Locate the fuel filter, typically found along the fuel line.
Relieve the fuel pressure by loosening the fuel cap and using a rag to catch any spills.
Disconnect the fuel lines from the filter using appropriate tools.
Replace the old fuel filter with a new one, ensuring proper alignment.
Reconnect the fuel lines and check for leaks.

4. Inspect and Replace Spark Plugs

Remove the ignition coil(s) by unscrewing the retaining bolts and disconnecting the electrical connector.
Remove the old spark plugs using a spark plug socket.
Inspect the spark plugs for wear or damage.
Install new spark plugs with a torque specification of 20 Nm (14.8 lb-ft).
Reattach the ignition coils and connectors.

5. Check for Vacuum Leaks

Visually inspect all vacuum hoses for cracks or disconnections.
Use a smoke machine or carburetor cleaner to test for leaks around the intake manifold.
Replace any damaged hoses or tighten loose connections.
