the final niggling issue

hi,

change the oil, topped off the coolant and put the belly pan on.
i only have one issue, (alreight there is always something like the
air horn which is in the mail but you know..).

i am having trouble with the idle. at times it is high 1200 other
times it is good ~800 put the a/c on and it is 0 unless you are
driving.

first off i would like to fix the a/c issue...i have heard it maybe
the iac(?) but i am uncertain...

any suggestions?

btw,
anyone near center connecticut?
