Solution

1. Preparation

Gather tools and materials.
Disconnect the negative battery cable to prevent electrical shorts.
Allow the engine to cool if it has been running.

2. Inspect and Replace Fuel Filter

Locate the fuel filter (usually along the fuel line under the vehicle).
Use a wrench to disconnect the fuel lines, taking care to catch any spilled fuel.
Replace the old fuel filter with a new one, ensuring correct orientation.
Reconnect the fuel lines and tighten them securely.

3. Check and Replace Spark Plugs

Remove the ignition coil covers, if necessary, using a socket set.
Disconnect the electrical connectors from the ignition coils.
Remove the spark plugs using a spark plug socket and ratchet.
Inspect the spark plugs for wear or deposits; replace with new plugs as needed.
Reinstall the ignition coils and reconnect the electrical connectors.

4. Clean Throttle Body

Remove the air intake duct to access the throttle body.
Spray throttle body cleaner inside the throttle body and use a soft cloth to wipe clean.
Ensure the throttle plate moves freely; reassemble the air intake duct.

5. Check for Vacuum Leaks

Inspect all vacuum hoses for cracks or disconnections.
Replace any damaged hoses and recheck connections to the intake manifold.
