X5 stalled/set codes while being inspected!

[workingonit]

I tested the X on my 10 mile course around the house, then followed that by taking videos of my dashboard display.

The X never stalled out, but stumbled four times, this time only on right turns and curves. I intentionally over-accelerated and whipped around them, just for maximum effect.

The STFTs at some points were as high as -28.5, again, while the LTFTs were between -7.03 and -8.59 (they were both at -8.59 when I started the drive). I took two videos of the display when i first returned to the driveway, and after awhile, I reset the MAF, and took two more. i don't understand the patterns shown by the O2 sensors, but when i graphed (and lost the graph) them on the drive, they looked better.

The first video had throttle% on the left, but the other three had RPMS in that space. i hope they'll open for y'all.

finally, I took a pic of the emission monitors, and there are still three incomplete (before I reset the MAF). If only one had remained, then I'd take it in for inspection and to heck witth the stumbles. The wife is going out of town tomorrow, so I won't be test driving until she gets back, so i have time to sit, think, and curse my fate.
