Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a level surface with the engine off and cool.
Safety warning: Disconnect the battery before working on electrical systems.

2. Inspect and Replace Spark Plugs

Remove the ignition coil or spark plug wires to access the spark plugs.
Use a spark plug socket to remove the spark plugs. Inspect them for wear or carbon buildup.
Replace any worn or damaged spark plugs with new ones, ensuring they are gapped to manufacturer specifications.
Reinstall the ignition coil or spark plug wires.

3. Check and Replace Fuel Filter (if applicable)

Locate the fuel filter according to the vehicle’s service manual.
Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect the fuel lines from the filter, being cautious of any residual fuel.
Replace the old fuel filter with a new one, ensuring proper orientation and tight connections.

4. Test and Replace Battery (if necessary)

Use a multimeter to check battery voltage. It should read around 12.6 volts when fully charged.
If the voltage is low, charge the battery or replace it if it fails to hold a charge.
Clean battery terminals and ensure they are tightened securely.
