I had my fingers crossed for an easy fix but....no such luck. I swapped the Lambda O2 sensor to the port farther down stream and no noticeable change in the surging while driving in closed loop. AFR readings on the wideband seems to jump all over the place when in closed loop, sometimes bouncing .8-1% in the matter if just a second, almost like the lambda system cant find the sweet spot.
