Sounds like your BAC valve.

The rotary makes almost no torque at low revs, so Mazda put a bunch of air bleeds to add power when accessory loads come on. Some are direct like the AC & PS. For everything else, when the computer sees a drop in revs, it pulses stronger on the BAC (bypass air control). When all this stuff is working, the idle is perfect.
