[Diy_efi] Interpreting ALDL data

[Scott Scott]

The "Low Battery" flag turned off when cruising the
car, so I dont think this one is a problem. 

I've been crunching the data stream numbers in excel
and they actually look fairly decent.  For some reason
the O2 sensor spits out a .004 every now and
then--sometimes 4 or 5 of those readings in a row.  Is
it a defective sensor?
