Solution
1. Preparation
  • Gather tools and ensure the vehicle is parked on a level surface.
  • Disconnect the battery to prevent electrical shorts during diagnostics.
2. Inspect Throttle Position Sensor (TPS)
  • Locate the TPS on the throttle body.
  • Disconnect the electrical connector from the TPS.
  • Use a multimeter to measure the resistance across the TPS terminals while moving the throttle plate from closed to fully open.
    • Resistance should vary smoothly without dead spots. If there are any irregularities, replace the TPS.
3. Check Mass Airflow Sensor (MAF)
  • Find the MAF sensor in the air intake duct.
  • Disconnect the electrical connector and remove the sensor.
  • Clean the MAF sensor using MAF cleaner spray. Avoid touching the sensor elements.
  • Reinstall the MAF sensor and reconnect the electrical connector.
4. Inspect Vacuum Lines
  • Visually inspect all vacuum lines connected to the intake manifold and throttle body.
  • Look for cracks, disconnections, or signs of wear.
  • Replace any damaged vacuum lines to ensure proper airflow and prevent leaks.
5. Transmission Fluid Check
  • With the engine running, check the transmission fluid level using the dipstick.
  • If low, add the manufacturer-recommended transmission fluid until it reaches the proper level.
  • If fluid is discolored or burnt, consider a transmission fluid change.
6. Reconnect Battery and Clear Codes
  • Reconnect the battery terminals.
  • Use the OBD-II scanner to clear any diagnostic trouble codes (DTCs).
  • Start the engine and observe for any returning codes or abnormal behavior.
