Thanks for the DME tip, I did find the website, yes, pricey, but 5 year warranty. Hopefully it isn't a DME unit.

I am running the CarCode OBD2 software which really isn't good for much of anything other than pulling the codes and clearing them. You can test the O2's which is nice, but I have noticed, the only O2 I can test is the one I replaced. Hmm, bank 1, position 1 is the pass, before cat right?

If that is true, maybe the 4 "new" ones installed just are not cutting mustard? I can smell it running rich at idle. Something isn't right. The one I did replace was direct fit Bosch from local parts store.
