    Code P0505 help

    I keep getting code P0505 for the idle control valve. I took the valve off today and it opens and closes. Does anyone else know what to look for? The car is a 2001 Corolla. Also when I start my car sometimes it idles really high and then almost dies for a second like its trying to idle down.

    Ever figure it out?

    Could just be an air intake hose loose.
    or
    your intake air control valve is stuck or closed.
    or
    wiring

    I bought another idle air control valve on ebay and it fixed the problem. Now im getting the P0420 code.

    What the...

    Go to a muffler shop and have them replace the cat and clear the light. If the light comes back on, go to the shop and have a factory rear 02 put in.

    I already had the cat replaced and the code was still there so I replaced the front 02 sensor and it's fixed for now.
