Solution
1. Preparation
  • Gather necessary tools and parts before starting.
  • Ensure the vehicle is parked on a flat surface and the engine is off.
  • Disconnect the battery to avoid electrical issues during repairs.
2. Inspect and Clean Throttle Body
  • Remove the air intake duct connected to the throttle body.
  • Use throttle body cleaner and a clean rag to remove carbon deposits from the throttle body.
  • Reattach the air intake duct securely.
3. Replace Throttle Position Sensor (if faulty)
  • Locate the throttle position sensor on the throttle body.
  • Disconnect the electrical connector.
  • Remove the screws securing the sensor and take it out.
  • Install the new throttle position sensor and secure it with screws.
  • Reconnect the electrical connector.
4. Check and Replace Spark Plugs and Ignition Coils (if necessary)
  • Remove the ignition coil cover (if applicable).
  • Unplug the ignition coils and remove them from the spark plugs.
  • Unscrew the old spark plugs using a spark plug socket and replace them with new ones.
  • Reinstall the ignition coils and reconnect the wiring.
5. Fuel System Inspection
  • Check the fuel pump operation by listening for the pump noise when the ignition is turned on (without starting the engine).
  • Connect a fuel pressure gauge to the fuel rail and verify the pressure against specifications.
  • Replace the fuel filter if clogged or if pressure is too low.
