Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the battery to ensure safety.
  • Allow the engine to cool completely before working on it.
2. Inspect and Clean the Throttle Body
  • Remove the air intake duct connected to the throttle body using a socket set.
  • Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
  • Reassemble the air intake duct and ensure all connections are secure.
3. Replace Spark Plugs
  • Remove the ignition coil covers using the appropriate socket.
  • Disconnect the electrical connectors from the ignition coils.
  • Remove the ignition coils and then unscrew the spark plugs using a spark plug socket.
  • Install new spark plugs with the correct gap, using the manufacturer’s specifications.
  • Reinstall the ignition coils and reconnect the electrical connectors.
4. Check and Replace Engine Coolant Temperature Sensor (if faulty)
  • Locate the engine coolant temperature sensor, typically near the thermostat housing.
  • Disconnect the electrical connector and unscrew the sensor using a wrench.
  • Install the new sensor and reconnect the electrical connector.
5. Test Fuel Pressure
  • Connect a fuel pressure gauge to the fuel rail test port.
  • Start the engine and observe the fuel pressure reading against manufacturer specifications.
  • If pressure is low, check the fuel pump and fuel filter for issues, replacing as necessary.
