Hi Nikki,
Your query begs the following questions:

Does the engine want to stall at lower RPM? If so it may be too lean at
idle. Perhaps your Mechanic had to lean it out for emissions, but maybe
it won't idle at that setting. Does the Cat glow red after a minute or two
of idling?

Since your '80 should have the electric cooling fan, what RPM does the
engine idle at with that fan on, along with the headlights, heater fan, and
brake lights operating? Mine drops about 300 RPM less, than if that
stuff is off. Still, the factory idle spec is 800 RPM.
Did he rebuild the carb or just reinstall it because of an emission
inspection?
Is your emission air pump operational?
If you are running a good Cat (not clogged or gutted) I can't see an idle
problem being caused by the Monza system. Did you use old parts or new to
restore the engine to standard?
