Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a flat surface and the engine is off.
  • Disconnect the battery to avoid electrical shorts.
2. Inspect and Replace Air Filter
  • Remove the air filter cover by unscrewing the fasteners.
  • Take out the air filter and inspect for dirt or damage.
  • Replace with a new air filter if dirty or damaged.
  • Reattach the air filter cover securely.
3. Fuel System Check
  • Connect the fuel pressure gauge to the fuel rail service port.
  • Start the engine and observe the fuel pressure reading; it should be within manufacturer specifications (typically around 30-50 PSI).
  • If the pressure is low, check the fuel pump and fuel filter; replace as necessary.
4. Throttle Body Cleaning
  • Remove the throttle body from the intake manifold (mark the position of the screws for reinstallation).
  • Use throttle body cleaner and a soft brush to clean the interior surfaces, ensuring no debris is left.
  • Reinstall the throttle body and reconnect any electrical connectors.
5. Spark Plug Replacement
  • Remove the ignition coil by unscrewing it from the engine.
  • Pull out the spark plug using a spark plug socket.
  • Inspect the spark plug for wear or carbon buildup; replace if necessary.
  • Reinstall new spark plugs and reattach the ignition coils.
6. Reconnect Battery and Test
  • Reconnect the battery terminals.
  • Start the engine and allow it to idle for a few minutes.
  • Test drive the vehicle to check for hesitation during acceleration.
