Solution
1. Preparation
  • Gather tools and parts needed for the repair.
  • Disconnect the negative battery terminal to ensure safety.
  • Allow the engine to cool before starting work.
2. Inspect and Replace Spark Plugs
  • Remove the ignition coil covers to access the spark plugs.
  • Use a socket wrench to carefully remove each spark plug.
  • Inspect the spark plugs for signs of wear, damage, or fouling.
  • Replace with new spark plugs (ensure to use the manufacturer’s specifications for type and gap).
3. Fuel System Inspection
  • Connect a fuel pressure gauge to the fuel rail Schrader valve.
  • Start the engine and observe the fuel pressure reading; it should meet the manufacturer’s specification (typically around 30-40 psi).
  • If low, check for fuel pump operation and fuel filter condition; replace if necessary.
4. Throttle Body Cleaning
  • Remove the throttle body assembly by disconnecting the air intake hose and electrical connectors.
  • Clean the throttle body using throttle body cleaner and a soft brush to remove carbon deposits.
  • Reinstall the throttle body and reconnect all hoses and connectors.
5. MAF Sensor Inspection
  • Disconnect the MAF sensor harness and remove the sensor.
  • Clean the MAF sensor with MAF cleaner, being careful not to touch the sensor element.
  • Reinstall the MAF sensor and reconnect the harness.
