Solution
1. Preparation
  • Gather tools and parts required for repair.
  • Disconnect the battery to ensure safety.
  • Allow the engine to cool before starting work.
2. Clean or Replace the Throttle Body
  • Remove the air intake duct connected to the throttle body.
  • Use throttle body cleaner and a soft brush to clean the throttle plate and surrounding areas.
  • Reinstall the intake duct ensuring all clamps are secure.
3. Fuel System Inspection
  • Locate the fuel pressure test port on the fuel rail.
  • Attach the fuel pressure gauge and turn the ignition key to the "On" position without starting the engine to check the pressure.
  • If pressure is below specifications, replace the fuel pump or filter as needed.
4. Inspect and Replace Ignition Components
  • Remove the engine cover to access the ignition coils.
  • Disconnect the electrical connectors and remove the ignition coils.
  • Inspect spark plugs for fouling or wear; replace if necessary.
  • Reinstall new or cleaned coils ensuring they seat properly.
5. Check for Vacuum Leaks
  • Visually inspect vacuum hoses for cracks or disconnections.
  • Use a smoke machine or spray soapy water on hoses while the engine is running to identify leaks.
  • Replace any damaged hoses.
