Yep picked up some parts had the codes read and says I need a sensor. Figure while I'm down there replacing the second 02 sensor in as many days. I might as well get it too, but the bolt will not back out. Spins over and over but no dice. Also there is a double connector ended cord from a part(sensor also maybe) in the trans forward from it but very near by that has a wire pulled also.
Any info, ideas or help appreciated.
Up date: So I went a head and removed the sensor housing (guess that's what it's called) still could not get it loose guess I will try and replace the whole thing. Still wondering what that unplugged/ broken connection part is and what it does.
