Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a flat surface and the engine is off.
  • Disconnect the negative terminal of the battery for safety.
2. Inspect and Clean Air Intake
  • Remove the air intake duct by loosening the clamps.
  • Inspect the air filter; replace if clogged.
  • Clean the throttle body using throttle body cleaner and a soft cloth.
3. Check and Replace Spark Plugs
  • Remove the ignition coils by unscrewing the retaining bolts.
  • Extract the spark plugs using a spark plug socket.
  • Inspect spark plugs for wear and replace with manufacturer-specified plugs if necessary.
  • Reinstall the ignition coils and secure with bolts.
4. Test and Adjust Fuel Pressure
  • Connect a fuel pressure gauge to the fuel rail.
  • Turn the ignition to the "ON" position without starting the engine and check the fuel pressure.
  • If pressure is below specifications, check the fuel pump and replace if faulty.
5. Reconnect Battery
  • Reconnect the negative terminal of the battery.
  • Ensure all connections are tight and secure.
