Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the battery to prevent electrical shorts during repairs.

2. Inspect and Replace the Fuel Filter

Locate the fuel filter, typically situated along the fuel line.
Use a wrench to relieve fuel pressure by loosening the fuel cap.
Disconnect the fuel lines from the filter, using safety glasses to protect eyes from fuel spray.
Replace the old filter with a new one, ensuring that the flow direction matches the arrows on the filter.
Reconnect the fuel lines securely.

3. Replace the Air Filter

Open the hood and locate the air filter housing.
Remove the clips or screws holding the housing cover.
Take out the old air filter and inspect for dirt or damage.
Install a new air filter, ensuring it's seated correctly.
Reassemble the air filter housing and secure it.

4. Inspect and Replace Spark Plugs

Remove the ignition coil or spark plug wires carefully to prevent damage.
Use a socket wrench to remove the old spark plugs.
Inspect the old plugs for wear or fouling. Replace with new spark plugs, ensuring proper gap specifications are met.
Reinstall the ignition coils or wires.

5. Check and Repair Vacuum Leaks

Inspect all vacuum hoses for cracks or disconnections.
Replace any damaged hoses with new ones.
If applicable, check the intake manifold gasket for leaks and replace if necessary.
