It is normal for the engine rpm to drop when the A/C is activated. Do the RPM's come back up when you turn the A/C off ?
My A/C is always on ,so I don't notice the drop. If for some reason it has been off and
when I turn it on,, I feel the load of the compressor. And RPM drop.
It is normal for it to do this. Don't panic. If for some reason you think it is an issue ,take it to the dealer.

It's fairly normal for rpm's to drop a little when AC is on or you put a load on the motor. Does it vibrate only when AC is on. You gotta AT right? I seem to recall some bad motor mounts causing vibration on AT's.

It could be the engine or trans mounts. How many miles on the car?
They changed mine at 23,000 miles on our old RX-8 AT.
This was due to a noise/rattle coming from under the car.
They installed both engine mounts and a tranny mount. But I did not notice any strong vibrations or any unusual vibrations at idle for that matter.

Get Mazda to replace the Engine Mount, they had some crappy material before and it will crack overtime.
after that, reflash your PCM to the newest one, if u'rs is a 04, it should be S, mine, a 05 looks like some F or something. 06 I dont know.
You're car should be fine as long as u do the above.
