Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during repairs.

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 clean the throttle plate and surrounding areas.
Reattach the air intake duct securely.

3. Check and Replace Spark Plugs

Remove the ignition coils using a socket set.
Extract the old spark plugs with a spark plug socket.
Inspect the plugs for wear and replace with new ones if necessary, ensuring they meet OEM specifications.
Reinstall the ignition coils and ensure they are properly seated.

4. Test and Replace Fuel Filter (if necessary)

Locate the fuel filter, typically in the fuel line.
Disconnect the fuel lines, using safety goggles to protect against fuel spray.
Replace the old fuel filter with a new one, ensuring proper orientation.
Reconnect the fuel lines and check for leaks.

5. Fuel Pressure Test

Connect a fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position (without starting the engine) to check for fuel pressure.
If pressure is below specifications, consider replacing the fuel pump.
