Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the negative battery terminal to ensure safety.
  • Allow the engine to cool before starting work.
2. Inspect and Replace Air Filter
  • Remove the air filter cover using a socket set.
  • Take out the old air filter and inspect it for dirt and blockages.
  • Install a new air filter (ensure it meets OEM specifications).
3. Fuel System Inspection
  • Attach the fuel pressure gauge to the fuel rail.
  • Turn the ignition to the "ON" position (without starting the engine) and check the pressure reading.
  • If pressure is below specifications, replace the fuel filter and inspect the fuel pump.
4. Throttle Body Cleaning
  • Remove the throttle body from the intake manifold (use a socket set).
  • Clean the throttle body with throttle body cleaner and a soft brush.
  • Reinstall the throttle body with new gaskets to prevent leaks.
5. Ignition System Check
  • Remove spark plug wires and inspect for wear or damage.
  • Replace spark plugs if they show signs of wear (gapped to manufacturer's specifications).
  • Check ignition coils with a multimeter for proper resistance; replace any faulty coils.
6. Exhaust System Inspection
  • Inspect the exhaust system visually for any signs of damage or blockages.
  • Check the catalytic converter for restrictions; replace if necessary.
