RE: o2 Sensors
Update: Found a code reader for the ODB-II that showed the voltages and such on the o2 sensors. They were both bad from what the reader was showing. So I ended up replacing them both.
Found 2 o2 sensors, both on the upstream after going ahead and jacking the rig up and crawling underneath. What gets me is why they have to put the connectors in such precarious spots. One I had to remove a panel to get to the connector. The other was behind/in part of the metal support frame and without an inspection mirror, you have to go by feel. But at least they are done now. Drove around most of Friday to help burn them in, boondocked the weekend and am driving back to home base today to do a few other repairs or patches that are needed before getting back on the road. Biggest thing to fix next is the support that the pull out step is connected to. The wood frame is breaking apart and needs rebuilt and a new tin box made to put around it.
