Well we tried all of the above and more and it still wouldn't budge. Almost finished off my torn shoulder the Dr says needs surgery on.
Thought about it some more. Got my kid to come over & help. Since the sensor was already busted up and only the nut remained, we got creative. Put a 7/8" 1/2" drive socket on the breaker bar. He held the socket on the nut and I got out the floor jack. We put the floor jack saddle so it would hit the breaker bar enough to move it "slowly". A screeching sound came from the sensor nut and after repositioning the breaker bar a couple of times the nut came out easy.
Found out there is a different plug between upstream and downstream sensors. Dealer gave me 2 upstream, but swapped one out for the downstream.
Got it going now and sounding sweet behind the wheel again. Might even improve my MPG now. Anyway both sensors are new CE light is off. Seemed some better today on a couple of short drives.
Appreciate the help.
