    My 92 Prelude revs up and down at idle speed from 1000 to 2000rpm when
    the temp is below 60 degrees. Does anyone know the cure for this
    illness?

    In my case, it was a bad O2. Others claimed insufficient coolant. Bleed
    the coolant and then get back?

    When your cooling system was last filled, was it bled of air?

    I have had the same problem with my 92 accord ex... in park and neutral it
    will rev up and down... i've looked it up elsewhere and they said it could
    be the idle air controller, which makes sense to me, and my mechanic
    pointed the part out to me that is bad, and it's connected to the fuel
    injector
