as i have stated in prior threads on this exact topic, 4cyl engines are not the most stable engines. the less cylinders = the more vibrations. also its got less power, so when the A/C clutch engages, it throws the engine into an imbalance. it stabilizes. i'd also clean your MAF sensor.
you didnt tell us a few key points:
1. do the lights dim when its vibrating?
2. how strong is this vibration?
3. whats the rpm before, during, after the vibration?
