Seems a lot of newer vehicles had a resistance reading in that ballpark but this O2 sensor must not be LT1 compatible or defective.

I have true plug and play O2 extensions coming on the 18th (instead of having them spliced since it makes me uncomfortable since it already caused an issue once). Tomorrow I'll switch the sensors around and my issue will most likely switch banks.
Resistance should be in ohms or milliohms, not millivolts. Is that what you meant?

As far as splicing into the O2 circuit itself, that can be tricky. Since the circuit itself runs from 0-1000mv any extra resistance from a funky solder joint will mess up the readings. I'd bet that the extensions will make a difference in your case.
