Erratic A/F ratio... fine one moment, LEAN the next >>

[tony4380]

hey guys.... im just wondering why my air fuel ratio is so jumpy... the car runs and drives fine. i went out for a drive today and to do some datalogging and i notcied that the air fuel ratio was rich...
so i thought to myself ok... thats probably just from being tuned back in december... with the temperature differences. so when i get a chance, i do a 3rd gear pull with column 9 calling for roughly 5 points taken out. i do so.
i then proceed to make another pull. A/F ratio was at like 15.3 so i back off. i monitor my A/F at part throttle. the whole time im driving around its 14.9 - 15.7. I stop, turn the car off then back on. A/F was fine... hovering around 14.3-14.5.
so i start driving again... A/F is fine. i give it some WOT and watch A/F... no higher than 13.7... hmm. when i ome to the red light i glance over and its idling at 15.2... and im thinkin WTF???

anybody have any ideas?? please help me guys.

thanks in advance

hard to give answers without a datalog showing the problem
