Solution
1. Preparation
  • Tools Required: OBD-II scanner, socket set, cleaning solvent, torque wrench, vacuum gauge, smoke machine.
  • Disconnect the negative battery cable to prevent electrical shock.
  • Allow the engine to cool down before beginning work.
2. Clean the Throttle Body
  • Remove the air intake duct connected to the throttle body.
  • Use cleaning solvent and a soft brush to clean the throttle body, ensuring that the butterfly valve operates smoothly.
  • Reinstall the air intake duct and securely fasten it.
3. Replace Spark Plugs
  • Remove the ignition coil assembly by unscrewing the bolts and disconnecting the electrical connectors.
  • Using a spark plug socket, remove the old spark plugs and inspect them.
  • Replace with new spark plugs, ensuring to use the correct gap specifications (typically 0.054 inches for most Ford engines).
  • Reinstall the ignition coils and torque to manufacturer specifications (usually around 10-14 ft-lbs).
4. Inspect for Vacuum Leaks
  • Visually inspect all vacuum hoses for cracks or disconnections.
  • Use a smoke machine to detect leaks by introducing smoke into the intake system.
  • Replace any damaged hoses or components as necessary.
5. Check Fuel Pressure
  • Connect a fuel pressure gauge to the fuel rail test port.
  • Turn the ignition to the "ON" position without starting the engine and record the fuel pressure.
  • Compare the readings to manufacturer specifications (typically between 30-50 psi for Ford vehicles).
  • If pressure is low, investigate the fuel pump, fuel filter, and pressure regulator.
