Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a level surface and the engine is cool.
  • Disconnect the battery's negative terminal to ensure safety.
2. Retrieve Diagnostic Codes
  • Connect the OBD-II scanner to the vehicle's diagnostic port.
  • Turn the ignition to the "On" position without starting the engine.
  • Record any trouble codes displayed on the scanner for reference.
3. Inspect and Replace Spark Plugs
  • Remove the engine cover if applicable to access the spark plugs.
  • Use a spark plug socket and ratchet to remove each spark plug.
  • Inspect for wear or fouling; replace any damaged plugs with OEM-spec plugs.
  • Torque the new plugs to manufacturer specifications (typically around 15-20 lb-ft).
4. Test and Replace Ignition Coils (if necessary)
  • Remove the ignition coil connectors and unbolt the ignition coils.
  • Inspect the coils for cracks or signs of arcing.
  • Replace any faulty coils with new OEM coils.
  • Reinstall the coils and connectors securely.
5. Check for Vacuum Leaks
  • Visually inspect all vacuum hoses and connections for cracks or disconnections.
  • Use a smoke machine or carburetor cleaner to identify leaks by spraying around suspected areas while the engine is running.
  • Replace any damaged hoses or seals.
6. Fuel System Pressure Check
  • Connect the fuel pressure gauge to the fuel rail test port.
  • Turn the ignition on (do not start the engine) and observe the gauge; it should read within the manufacturer's specified range.
  • If the pressure is low, check the fuel pump and filter for issues and replace if necessary.
