So after driving 2000 miles this previous week and monitoring everything with Torque, I have came to the conclusion that my bank 2 sensor 2 is gone. It would just stick on lean after 10 minutes of expressway driving after every stop for gas... so it sounds like it is time to change it out.
I see all kinds of options out there including the "universal 4 wire" option that I am assuming you chop and splice the existing wire... anyone have any luck going this route? or do anyone have any words of wisdom to share when changing the O2 sensors in our beasts?
Thanks for your help
