Solution

1. Preparation

Gather tools and parts needed for repair.
Disconnect the battery to prevent any electrical shorts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.

2. Inspect and Replace Fuel Filter

Locate the Fuel Filter: Depending on the model, it may be located in the fuel tank or along the fuel line.
Remove the Fuel Filter:
- Use a wrench or socket set to disconnect the fuel lines.
- Remove any retaining clips.
Install New Fuel Filter:
- Position the new filter in place and secure it with clips.
- Reconnect the fuel lines securely.
Check for Leaks: Turn the ignition to the 'ON' position (without starting) to pressurize the system and check for leaks.

3. Inspect and Replace Spark Plugs and Ignition Coils

Access the Ignition Coils: Remove engine cover if applicable.
Remove Ignition Coils:
- Disconnect the electrical connectors from each coil.
- Remove the bolts holding the coils using a socket set.
Replace Spark Plugs:
- Use a spark plug socket to remove old spark plugs.
- Check the gap on new spark plugs and install them.
Reinstall Ignition Coils: Secure coils back in place and reconnect electrical connectors.
Reassemble Engine Cover: If removed, replace the engine cover.

4. Check for Vacuum Leaks

Visual Inspection: Look for any cracked or disconnected vacuum hoses around the intake manifold.
Spray Method: Use carburetor cleaner or soapy water to spray around suspected areas while the engine is idling; changes in RPM will indicate leaks.
Replace or Repair: Replace any damaged hoses and secure loose connections.
