Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a flat surface and the engine is cool.
  • Disconnect the battery to prevent electrical shorts.
2. Inspect and Replace Spark Plugs
  • Remove the ignition coils using a socket set.
  • Extract the spark plugs using a spark plug socket.
  • Inspect the spark plugs for wear, carbon buildup, or damage.
  • Replace with new spark plugs (manufacturer specifications recommended).
  • Reinstall ignition coils and reconnect battery.
3. Clean Throttle Body
  • Disconnect the throttle body connector and remove the throttle body assembly.
  • Use throttle body cleaner and a soft brush to clean the interior surfaces.
  • Reinstall the throttle body, ensuring all gaskets are intact.
  • Reconnect the electrical connector.
4. Check and Repair Vacuum Leaks
  • Inspect all vacuum hoses for cracks or disconnections.
  • Replace any damaged hoses.
  • Use a smoke machine or carburetor cleaner to identify leaks if necessary.
5. Test and Clean Fuel Injectors
  • Use a fuel pressure gauge to check for proper fuel pressure.
  • If pressure is low, inspect the fuel filter and fuel pump.
  • If injectors are clogged, use a fuel injector cleaning kit or replace if necessary.
