90 80q/AC idling?

[lester]

Well, my AC is still working in my 90 80q, however, at idle, with the AC on, the throttle seems to be "searching" up and down for the correct idle rpm? Isn't there a sensor, so when there is a load on the engine at idle [for the AC] that accommodates a little higher idle?
TIA Bob
