Solution
1. Preparation
  • Gather tools such as an OBD-II scanner, multimeter, cleaning supplies, and any required replacement parts.
  • Ensure the vehicle is parked on a level surface and the engine is cool to the touch.
2. Clean the Throttle Body
  • Sub-steps:
    1. Disconnect the negative battery terminal to ensure safety.
    2. Remove the air intake duct connected to the throttle body.
    3. Use throttle body cleaner and a soft cloth or brush to clean the inside of the throttle body thoroughly.
    4. Reattach the air intake duct securely.
3. Inspect and Clean the IAC Valve
  • Sub-steps:
    1. Locate the IAC valve, typically found on or near the throttle body.
    2. Remove the IAC valve connector and unscrew the mounting bolts.
    3. Clean the IAC valve with throttle body cleaner, ensuring the passages are clear.
    4. Reinstall the IAC valve, securing it with the bolts and reconnecting the electrical connector.
4. Test and Repair Fuel System
  • Sub-steps:
    1. Connect a fuel pressure gauge to the fuel rail and turn the ignition to the "ON" position without starting the engine.
    2. Check if the fuel pressure is within the manufacturer's specification (usually 30-50 psi for a Camry).
    3. If pressure is low, inspect the fuel pump and filter for blockage or failure. Replace as necessary.
5. Examine Vacuum Lines
  • Sub-steps:
    1. Visually inspect all vacuum lines for cracks or disconnections.
    2. Replace any damaged lines with new vacuum hose.
    3. Recheck for any remaining leaks and ensure all connections are secure.
