I have a 2003 GMC Z71 and twice this year the O2 sensor has failed, what causes the premature failure? Any feedback out there, thanks.

question, when you go to your repair shop and describe the ailments of your auto you would think that a honest facility would do the correct diagnosetics. In this case what would would you ask the repair facility to check?
exactly what it is dooin'.............. Check engine lite is on, and running rough and black smoke.
So in other words, this isn't necessarily the 2nd o2 sensor, you're just guessing it is, at this point???
i'm taking an educated guess that it is the sensor as the symptoms are the same as last time.
was just going to say that,what about the other 3 o2 sensors?

no were does general motors say to replace o2 sensors every 80k.they are very common to go.even the gm oem ones.if it is another o2 then it should be warranty if its under a year.i work at gm and not to often do i see o2 sensors go out because of a fuel problem.etc.get is scanned then go from there
it goes in thursday to get scanned and diagnosed, if it is the same sensor hopefully the gm dealership replaces it under warranty.
ouch it should have been .5 max diag not 1.3 and .3 to replace,next time come over to nicholson or go see summitric,i have seen o2's cause bank 1 sensor 1 to run so rich it fouled the plugs but not the other way
