I had AutoZone scan the car and these codes came up, both relating to the O2 sensor. I'm going to borrow a scan tool from a guy and erase the codes and see if anything comes back. I'm just afraid that the new O2 sensor I just put in is now junk (it was a Bosch). Perhaps it got contaminated by something burning off the engine (such as PB Blaster, coolant, etc.) Any thoughts?

I'm surprised that Bosch O2 sensors and plugs work so poorly in these engines.
I've worked on all kinds of diesel equipment with Bosch components: Injectors, injection pumps, relays, glow plugs, switches, sensors... and in my experience, Bosch products are hard to beat.
But I steer clear of them for my own GM V6's.

Ooops, apparently I haven't been around long enough. I have a pair of Bosch O2 sensors coming in today. The ACDelco were about twice as much ($100+ ea) and my engine takes two! Oh well...'98 Volvo V90 - Ford 5.0 swap in progress

Bosch has high and low end stuff. I work in engine R&D, (diesel, gas, hydrogen, etc.) and the expensive bosch stuff is top of the line, while the replacement stuff you get from the parts store seems to suck major.

I put the new AC sensor in, sprayed the MAF off with electronics cleaner, and then cleared the codes. After that I drove around for 30 minutes, stopped the car and restarted, drove some more, etc. I got back home and plugged the scanner in and the codes haven't reappeared. I guess I'm feeling pretty good right now and hope that this is it for a while. I still have to change the fuel filter and I noticed that the PCV valve I currently have is really noisy. I guess I'll change that also.
