Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Clean Throttle Body

Remove the air intake duct to access the throttle body.
Use throttle body cleaner and a soft cloth to remove carbon deposits from the throttle body.
Reinstall the air intake duct securely.

3. Check and Replace Fuel Filter

Locate the fuel filter (if applicable) and disconnect the fuel lines using caution to avoid fuel spillage.
Replace the fuel filter with a new one, ensuring proper orientation and secure connections.
Reconnect the negative battery terminal.

4. Inspect and Replace Spark Plugs

Remove the ignition coils by unscrewing them from the engine block.
Take out the old spark plugs using a spark plug socket.
Inspect the spark plugs for wear and replace them with OEM specifications.
Reinstall the ignition coils and torque them to the manufacturer's specifications.

5. Test and Replace Battery (if necessary)

Use a multimeter to check the battery voltage; it should be above 12.4 volts.
If the voltage is low, replace the battery with a compatible unit and ensure proper connections.
