Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface.
Disconnect the negative battery terminal to prevent electrical shock.

2. Check and Replace Gas Cap

Remove the gas cap and inspect for cracks or wear.
Replace with a new gas cap if necessary.
Reinstall the gas cap securely.

3. Replace Spark Plugs

Remove the ignition coil cover using a socket set.
Disconnect the ignition coils and pull them out.
Remove spark plugs using a spark plug socket and ratchet.
Inspect the old spark plugs for wear; replace if necessary.
Install new spark plugs with the recommended torque (usually around 13-15 ft-lbs).

4. Inspect and Replace Air Filter

Locate the air filter box and open it.
Remove the old air filter and check for dirt and debris.
Install a new air filter ensuring it is seated properly in the housing.

5. Check for Vacuum Leaks

Inspect vacuum hoses visually for cracks or disconnections.
Use a smoke machine or carburetor cleaner to check for leaks.
Replace any damaged hoses.
