Stumped on this one, maybe someone can send me in the right direction. Goes 10 or 11 AFR at 0% TPS, then corrects as soon as throttle is pressed. As speed slows while decelerating at 0% TPS, the AFR slowly gets better until it is fine again at lower speeds. AFR at idle is ok. 3 Bar, LS3, twins, turbo cam, 4L80.
