anyways, is the problems i have with my o2 sensor because of other reasons? I mean the o2 sensor i think is the same one that probably came on the car brand new so i would assume its got about 80-90K on it. Is it just be chance that it decided to crap out just when i swapped my motor and was having other problems or could it be from other problems? Like if the car runs too rich or too lean because of say.....theres not actually enough fuel getting into the engine (i.e. Bad, clogged injectors) would it jam up the o2 sensor from getting too hot from the lean conditions? Stuff like that.....is there things that will literally break a new o2 sensor because i dont want to buy a new one and then have it crap out on me because i didnt fix the "real" problem.
