RE: Fluctuating Idle / more info.

["Livolsi, Stephane" <livols1@investorsgroup.com>]

I'm just flapping at the gums here but.... have you checked the climate
control sensors/senders, etc?  When I turn the climate control on
anything but econo, the idle kicks up.  If you have a faulty connection
there, maybe it's causing your problem?... just thinking aloud...
