These codes according to the toyota repair manual are "system too rich". It sounds like your "Intake Idle Air Control Valve". After years of running these can get carboned up. You can try to remove the IIACV and clean it with carb and choke cleaner then reinstall it. This has been known to fix it. If it doesn't you will needs to replace the unit. My 02 had a problem of not starting and uneven ideling, I could get it to start by pumping the pedal. I cleaned the unit and it is working perfectly a year later. Hope this helps. If it does just go to Auto Zone or Advance Auto and they can delete the codes once you fix the issue for free.
