Test3 .98 at idle both banks (durametric only specifies oxygen sensors cyl 1-3 and cyl 4-6 don't know if its pre or post))

Test3a (Same as 3 but at a different time) seemed somewhat erratic but what do I know.

Somehow my CEL cleared itself while testing. It was not reset cause all my readiness tests all passed when I checked ie. heater/cats/secondary air etc...

sent a PM as well ....I have a video using my torque light on my droid if you're interested. Thanks Again....V
Ok lets try to simplify this :
Just do a running test.
You want to check the same two boxes you checked in the first test. look at the first graph you posted.
They say: O2 sensor voltage ahead of cat. conv. bank 1
O2 sensor voltage ahead of cat. conv. bank2
Also find: O2 sensor voltage behind cat. conv. bank 1
o2 sensor voltage behind cat. conv. bank 2

with those four boxes checked do the running test with the car warmed up and at idle.

Make sure your testing "VOLTAGE" not oms or anything but voltage



Then post the graph
