P1151 OBD II DTC error code
 
HO2S Bank 2 Sen 1 Insuff. Switching Lean Mean is the DTC code. Which O2 sensor does this mean? Is it anything to worry about or was my daughter just following a Diesel truck putting out some smoke?

You want to replace the o2 sensor opposite cyl#1 befor the cat. YesI would replace it will save some pennies in gas.

I got this code after loading my explorer up while helping someone move. I got bad gas mileage because of the weight, and it threw the 1151 code. I reset it and did normal highway driving. The light came back and I am getting 22 mpg in my 96 Explorer V6. That is pretty much the peak of my good fuel economy. Why would I still be getting such good gas mileage?

Any info would be great.

22 mpg?? I'd die for that. My daughter gets 14 mpg, maybe 17 if I put Marvel Mystery Oil in. If it cost 30 bucks for an O2 sensor to get 6 - 8 mpg more that wouldbe great. By the way, I reset the code and haven't seen it since.
