Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to ensure safety during repairs.

2. Inspect and Replace Fuel Filter

Locate the fuel filter (usually near the fuel tank or along the fuel line).
Use a wrench to disconnect the fuel lines from the filter.
Remove the old fuel filter and install the new one, ensuring proper orientation.
Reconnect the fuel lines securely.

3. Clean or Replace Throttle Body

Remove the air intake duct to access the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
If cleaning does not resolve the issue, remove the throttle body and replace it with a new unit.
Reinstall the air intake duct securely.

4. Replace Spark Plugs

Remove the ignition coils by unbolting them and disconnecting the electrical connectors.
Unscrew the old spark plugs using a spark plug socket and ratchet.
Install new spark plugs, ensuring they are gapped correctly per manufacturer specifications (typically around 0.043 in).
Reinstall the ignition coils and secure them in place.

5. Check and Replace Battery if Necessary

Use a multimeter to check the battery voltage (should read around 12.6 volts when fully charged).
If the voltage is low, consider replacing the battery with a new one as per manufacturer specifications.
