My daughter has a 2006 Sebring with a 2.7. It needs an O2 sensor downstream. Code P0157. This thing is going to be a SOB to change, to the point I may have a garage do it. There just isn't room to do this easily. Does anybody have any helpful hints or advise before I have to fork out $90.00 dollars an hour for something I should be able to do in my garage? If you saw where it's located you'd see what I mean. Thanks to any who respond. G.P.
