Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Disconnect the battery to ensure safety while working on electrical components.
2. Replace Air Filter
  • Remove the air filter housing cover using a socket set.
  • Take out the old air filter and inspect the housing for debris.
  • Install a new air filter, ensuring it fits snugly.
  • Reattach the air filter housing cover and secure it with the appropriate fasteners.
3. Fuel Pressure Check
  • Connect the fuel pressure gauge to the fuel rail service port.
  • Turn the ignition to the "On" position (do not start the engine) to check the fuel pressure reading against specifications.
  • If the reading is below the specified range, consider replacing the fuel pump or checking the fuel filter for clogs.
4. Inspect and Replace Ignition Components
  • Remove the spark plug wires and carefully take out the spark plugs using a spark plug socket.
  • Inspect the spark plugs for wear, carbon buildup, or damage; replace them if necessary.
  • Check the ignition coils for faults and replace any that are not functioning correctly.
  • Reinstall the spark plugs and reconnect the ignition wires.
5. Clean Throttle Body
  • Remove the throttle body from the intake manifold by unscrewing the fasteners using a socket set.
  • Use throttle body cleaner and a soft cloth to clean the interior surfaces.
  • Reinstall the throttle body, ensuring proper alignment and torque to manufacturer specifications.
6. Check for Vacuum Leaks
  • Inspect all vacuum hoses for cracks, frays, or disconnections.
  • Replace any damaged hoses and ensure all connections are secure.
