Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuel Filter

Sub-steps:
- Locate the fuel filter; refer to the vehicle's service manual for specific location.
- Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
- Disconnect the fuel lines from the filter using a fuel line release tool.
- Remove the fuel filter from its mounting bracket.
- Install the new fuel filter, ensuring the flow direction is correct.
- Reconnect the fuel lines and ensure they are secure.

3. Check and Replace Spark Plugs

Sub-steps:
- Remove the ignition coil covers if applicable.
- Disconnect the wiring harness from each ignition coil.
- Remove the ignition coils using a socket set.
- Remove old spark plugs with a spark plug socket.
- Inspect the spark plugs for wear; replace if necessary.
- Install new spark plugs, using a torque wrench to tighten them to the manufacturer's specification (typically around 13-15 ft-lbs).
- Reinstall ignition coils and reconnect the wiring harness.

4. Inspect Battery and Charging System

Sub-steps:
- Use a multimeter to check the battery voltage (should be around 12.6 volts when fully charged).
- Inspect battery terminals for corrosion and clean if necessary.
- Start the vehicle and check the alternator output with the multimeter (should be between 13.5-14.5 volts).
- Replace the battery or alternator if either is found faulty.
