theory: my lope/hunt a few minutes after cold start and the intermittent low
lope when warm are caused by the same thing, the AAR. Could it be so that the
AAR is too open when cold and intermittently closes too much when warm so that
my base idle setting will all of a sudden be too low for the more closed AAR?
And that when the AAR opens up a wee bit more my idle comes back?<BR><BR>I
guess I’m wondering if that’s mechanically possible or sounds at all
reasonable.</FONT></BLOCKQUOTE>

<DIV>Yes and No. Yes the AAR can cause the loping idle when warm, but,
that's only because the AAR is almost closed. Usually the loping idle is
swinging from bumping up to the 1400 rpm rev limit, and dropping off to around
750 to 800 rpms (just bouncing between the 2). A low idle loping sounds like
something is off in the timing or elsewhere. </DIV>
<DIV>Now, if the AAR is not closing fully, the idle speed will still be higher
than normal, and if the idle speed was set while the AAR was still open it's
possible that when the valve closes (your intermittent low idle), that you would
see a low idle condition. Personally, I've never run into this situation, as
mine has always been too high of an idle speed.</DIV>
<DIV>I don't know if this helps or not.
