Durametric Troubleshooting of P1124,1126, and 0130

[runjmc2]

After much searching I have not found any clear answers. The car is running fine and I did a quick scan prior to the smog test. The P1124/1126/0130 came up, no CEL. After looking up the codes I hooked up the Durametric with the following results that I believe are most relevant to the situation.

The 02 sensor ahead of the cats, both banks, both look very sloppy. Sharp (up/down) and then slow reaction to both the high or low voltage. No real pattern just a choppy graph, not at all like the typical wave pattern I have seen....and I even played with the sample rate (fast/slow) and nothing smoothed the curves. In addition the values went below .1 on many occasion.

To ensure I am not missing any other "root" causes (e.g. air leak or fuel delivery issue) I checked the FRA and TRA (which best I can tell is the German version of Short and Long term Full Trim. I believe these are "normal" and do not indicate either a fuel delivery and intake air leak. The values I get are:

FRA/FRA2 - 1.03 (steady and the same for both)
TRA (.13) and TRA2 (.11) both steady

My conclusion is that it is simply the upstream O2 sensors and there is no other root issue. Any other thoughts on conclusions or other sensor I should have monitored? Thanks!!!
