    I am buying a 1999 Accord with the V6. The idle is oscilating between 1100 and
    1900 rpms at an idle after it warms up. The check engine light is also on. Any
    ideas? How hard to fix? Cost? It is at an auction, so if I want the car I have
    to fix it myself.
    Thanks

    Possibly a bad oxygen senor? What code are you getting?

    Haven't had the codes pulled yet. I guess that is the first thing I need to get
    done.
    Thanks

    Yes, get the ECU codes or go on a test drive. The ECU raises the idle
    speed to whatever keeps the engine running smoothly. The fast idle
    throbbing could anything from a leaky injector to a cracked engine block.

    It's a bad IAC (Idle Air Control valve). It's mounted under the throttle
    body. See this alot.

    it'll be a p0505 iac fault. if it's low on coolant it'll do this. tap
    the iac with a small hammer while it's running, most of the time it
    will unstick and run for another year.
