Narrative:
We were flying LNAV to avsar intersection and getting numerous speed reductions for preceding traffic. At that time we also encountered towering cumulus and had to turn the eai (engine anti-ice) on. The controller gave that traffic a turn away from our path and gave us further decent to that aircrafts altitude of 12000 ft. The controller than issued us a left turn to 110 degrees for one min then back direct to avsar intersection. As I looked up to turn the aircraft to 110 degrees the stick shaker activated very briefly. As the capt. Was talking on the radio and looking outside for traffic I responded with immediate thrust and recovery. We both debrief this item and both agreed on how and why this happened. I can tell you I learned a valuable lesson on the importance of keeping my eye on the airspeed indicator; especially when the auto pilot is on; the aircraft is in a turn; and flying at clean maneuvering and the aircraft is flying below the flight path in the FMC.
