Solution
1. Preparation
  • Gather tools and parts.
  • Disconnect the negative terminal of the battery to avoid electrical shorts.
  • Ensure the engine is cool before starting work.
2. Inspect and Replace Spark Plugs
  • Remove the engine cover (if applicable) using a socket set.
  • Disconnect electrical connectors from the ignition coils.
  • Remove the ignition coils using a socket set.
  • Extract the old spark plugs using a spark plug socket.
  • Inspect for wear, deposits, or damage.
  • Install new spark plugs to the manufacturer’s torque specification (typically 18 ft-lbs).
  • Reinstall ignition coils and reconnect electrical connectors.
  • Replace the engine cover.
3. Clean Throttle Body
  • Remove the air intake duct connected to the throttle body.
  • Use throttle body cleaner and a soft cloth to clean the throttle plate and bore.
  • Ensure the throttle plate operates freely.
  • Reattach the air intake duct securely.
4. Address Fuel Delivery Issues
  • Connect a fuel pressure gauge to the fuel rail.
  • Start the engine and check the fuel pressure against manufacturer specifications (typically 50-60 psi).
  • If pressure is low, inspect the fuel filter and fuel pump for proper function.
  • Replace the fuel filter if it is clogged.
5. Replace Engine Coolant Temperature Sensor (if necessary)
  • Locate the engine coolant temperature sensor and disconnect its electrical connector.
  • Remove the sensor using a socket set.
  • Install the new sensor and reconnect the electrical connector.
  • Refill any lost coolant and bleed the cooling system if necessary.
