That's because the AC put a load on the motor and moved the idle to a different/richer part of the VE table. Suggests to me that your oscillating idle is due to a lean surge. The VE table at idle needs to be flattened out, probably along w the SA table altho I would look at Closed Throttle Idle SA setting.
