Solution
1. Preparation
  • Gather required tools and parts.
  • Disconnect the battery to ensure safety while working on electrical components.
2. Air Filter Replacement
  • Remove the air filter housing cover:
    • Tools: Socket set
  • Replace the old air filter with a new one.
3. Clean Throttle Body
  • Remove the throttle body from the intake manifold:
    • Tools: Socket set
  • Use throttle body cleaner and a soft brush to clean internal surfaces.
  • Reinstall the throttle body and ensure all connections are secure.
4. Fuel Pressure Check
  • Connect the fuel pressure gauge to the fuel rail:
    • Tools: Fuel pressure gauge
  • Start the engine and check that the pressure is within manufacturer's specifications. If low, replace the fuel pump.
5. Ignition System Inspection
  • Remove and inspect spark plugs for wear or fouling:
    • Tools: Socket set, spark plug socket
  • Replace any faulty spark plugs and ignition coils as necessary.
6. Exhaust System Inspection
  • Visually inspect the exhaust system for any signs of obstruction or damage.
  • If a clogged catalytic converter is suspected, perform a back pressure test and replace if necessary.
