1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety.
Allow the engine to cool if it has been running.

2. Address Fuel Delivery Issues

Check Fuel Filter:
- Locate the fuel filter.
- Replace it if it is clogged or due for replacement.
Inspect Fuel Pump:
- Remove the fuel pump access panel if applicable.
- Test the fuel pump operation using a multimeter.
- Replace the pump if it does not operate within specifications.

3. Replace Spark Plugs and Ignition Coils

Remove Ignition Coils:
- Unplug the electrical connectors and remove mounting bolts.
- Carefully lift out the ignition coils.
Replace Spark Plugs:
- Use a spark plug socket to remove old plugs.
- Gap new spark plugs according to manufacturer specifications and install.
Reinstall Ignition Coils:
- Place coils back into their respective positions and secure with bolts.
- Reconnect electrical connectors.

4. Clean or Replace Air Filter

Remove Air Filter Housing:
- Unclip or unscrew the air filter housing.
- Take out the air filter.
Clean or Replace Filter:
