Solution
1. Preparation
  • Gather necessary tools and parts.
  • Park the vehicle on a level surface and engage the parking brake.
  • Disconnect the battery to ensure safety.
2. Clean or Replace Air Filter
  • Remove the air filter cover using a socket set.
  • Take out the air filter and inspect it.
  • If dirty, replace it with a new one or clean it if reusable.
  • Reattach the air filter cover securely.
3. Check and Clean Throttle Body
  • Remove the throttle body air intake duct by loosening the clamps.
  • Disconnect the electrical connector from the throttle body.
  • Remove the throttle body using a socket set.
  • Clean the throttle body with throttle body cleaner and a soft cloth.
  • Reinstall the throttle body and reconnect the electrical connector.
4. Inspect and Replace Spark Plugs
  • Remove the ignition coil connectors.
  • Unscrew the ignition coils using a socket set and pull them out.
  • Remove the old spark plugs using a spark plug socket.
  • Install new spark plugs, ensuring proper torque (typically 13-15 ft-lbs).
  • Reinstall the ignition coils and connectors.
5. Check Fuel Pressure
  • Attach a fuel pressure gauge to the fuel rail.
  • Start the engine and observe the fuel pressure reading; it should match manufacturer specifications (typically around 40-50 psi).
  • If pressure is low, check the fuel pump and filter; replace if necessary.
