Solution
1. Preparation
  • Tools Required: OBD-II scanner, fuel pressure gauge, multimeter, socket set, torque wrench.
  • Disconnect the negative battery terminal to prevent electrical shorts during repairs.
  • Ensure the vehicle is parked on a flat surface and the engine is cool.
2. Check and Replace Air Filter
  • Remove the air filter cover using a socket set.
  • Inspect the air filter for dirt and debris; replace it if it appears clogged.
  • Reinstall the air filter cover securely.
3. Fuel System Inspection
  • Tools Required: Fuel pressure gauge.
  • Locate the fuel rail and attach the fuel pressure gauge.
  • Turn the ignition key to the “ON” position (do not start the engine) to check fuel pressure.
  • If pressure is below specifications, replace the fuel pump and/or fuel filter as needed.
4. Inspect and Replace Spark Plugs
  • Remove the ignition coil(s) using a socket set.
  • Take out the spark plugs using a spark plug socket.
  • Inspect the spark plugs for wear; if they are fouled or worn, replace them with new ones (ensure correct gap).
  • Reinstall the spark plugs and ignition coil(s), torquing to manufacturer specifications.
5. Throttle Position Sensor Adjustment
  • Tools Required: Multimeter.
  • Disconnect the electrical connector from the TPS.
  • Use a multimeter to test the voltage output of the TPS while slowly moving the throttle.
  • If readings are inconsistent or out of specification, replace the TPS and reconnect it.
