Random Rich AFR

[jesus]

My car has been going rich out of no where at high speed low load and i cant seem to find whats causing it to happen. I've attached a log of the car going rich (12) then coming back out to (14). If anyone sees something I'm not please let me know.

fix to this if anyone finds it helpful was my secondary o2 sensor was reading outside air due to me leaving it plugged in since i had my aem AFR gauge plugged into the secondary bung. This would make the car run rich and after putting it back in everything was all good
