Solution

1. Preparation

Gather 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 (typically found in the fuel line or near the fuel tank).
- Disconnect the fuel lines carefully, using a rag to catch any spilled fuel.
- Remove the old fuel filter and replace it with a new one, ensuring correct orientation.
- Reconnect the fuel lines and check for leaks.
Tools Required: Fuel line disconnect tool, socket set.

3. Check and Replace Spark Plugs and Ignition Coils

Sub-steps:
- Remove the ignition coil covers if applicable.
- Disconnect the electrical connectors from the ignition coils.
- Remove the ignition coils and inspect for cracks or damage.
- Replace any faulty ignition coils with new ones.
- Remove old spark plugs and install new ones, torqueing to manufacturer specifications (typically around 13-15 lb-ft).
Tools Required: Socket set, torque wrench, spark plug socket.

4. Inspect Air Intake and Replace Filter

Sub-steps:
- Remove the air intake duct to access the air filter.
- Inspect the air filter for dirt and clogging; replace if necessary.
- Check the intake ducts for blockages or cracks and replace or repair as needed.
Tools Required: Screwdriver set.

5. Test and Replace Battery if Necessary

Sub-steps:
- Use a multimeter to check the battery voltage. A healthy battery should read around 12.6 volts when the engine is off.
- If the voltage is low, consider replacing the battery with one that meets OEM specifications.
Tools Required: Multimeter.
