Solution
1. Preparation
  • Gather all required tools and parts.
  • Ensure the vehicle is parked on a level surface and the engine is cool.
  • Disconnect the negative battery terminal to prevent electrical issues.
2. Throttle Position Sensor Inspection
  • Locate the throttle position sensor on the throttle body.
  • Disconnect the electrical connector from the TPS.
  • Use a multimeter to test the TPS for proper voltage readings while moving the throttle plate:
    • Expected voltage should smoothly transition from approximately 0.5V to 4.5V as the throttle is opened.
  • If the readings are outside of this range, replace the TPS.
3. Cleaning the Throttle Body
  • Remove the air intake duct to access the throttle body.
  • Use throttle body cleaner and a soft cloth to clean the throttle body inside:
    • Focus on the butterfly valve and surrounding areas.
    • Do not use any abrasive materials.
  • Reattach the air intake duct securely.
4. Fuel System Check
  • Connect a fuel pressure gauge to the fuel rail.
  • Turn the ignition key to the "ON" position (do not start the engine) to check the fuel pressure.
  • Compare the reading to the manufacturer specifications; it should typically range from 30 to 50 psi.
  • If pressure is low, consider replacing the fuel pump or the fuel filter if it is clogged.
5. Inspect for Vacuum Leaks
  • Inspect all vacuum hoses for cracks or disconnections.
  • Use a smoke machine or carburetor cleaner to find leaks:
    • Spray around suspected areas and listen for a change in engine RPM.
  • Replace any damaged hoses or seals.
