    Dude I had the same issue had to borrow a adjustable crescent to swap mine out when I put in the pipebomb so I have no room to make fun. I don't think any harm will come I drove mine for 5 or 6 months and had to clear the code 5 or6 times. If it throws a p0152 then you will know the sensor is bad but if it throws the same code I would look into an exhaust leak somewhere

    Ok i got board and ended up getting them both off with a 7/8th wrench, but on the drivers side the rear has a longer cable so they couldnt be interchanged. the short passanger side couldnt reach the other side. so what I did after was I unpluged the passagner harness and started the truck and threw the same code. So this leads me to believe that my passanger side 02 sensor is bad.
