[UnSafe]

Thanks for the input.

I don't think it's running too rich, it only occurs when the AC is on, but will search for rich/ lean diagnostic stuff. It drops to a consistant and smooth idle when the AC is off.

As for adjusting the idle up a notch, is it simply a throttle stop screw adjustment, or something more involved? My Bentlys book is in the car right now and my wife is out driving it.
