When my car idles, my o2 flucuate normally and my BLM is at about 135. But under throttle my o2 drops down do 0 volts and my BLM skyrockets to 160, both indicating a lean condition. A few weeks ago when I had my scanner on it all was normal and since then I added nothing or changed nothing. What do you guys think? BTW if you want a copy of my Moates log file to help diagnose ill send it to you.

EDIT: I got some web space, here is a link to the excel log file.
