just found out today that my car's check engine light keeps coming up (even after removing my GIAC X-Chip and BOV and replacing BOV with Bailey BPV)
folks at AWE told me the fault was due to Oxygen Sensor...
can anyone tell me what that means? and what i can do? the last time i brought the car to the dealer, they told me it was due to chip and charged me $75 just inspecting it..
could that have been due to my GFB BOV?

Its a probe kind of sensor with some holes...it reads a voltage...pretty percise kind of deal. They can go bad.

is it or was it related to BOV that was installed before i replaced it with BPV?
is it fixable? then how? please help me... thank you

been there done that tried it on the dyno...pretty much a no-no.

Running rich can send both unburnt and a whole lot of carbon hitting the 02 sensor. I've heard of many people ruining them.

Even though I have ran rich, my sensor even got dipped in CV boot grease and still has been bulletproof. Looks like yours wasn't:-(.

so basically my car ran so rich for awhile that it messed up the sensor? has to be replaced?
****.. i bet you the dealer won't even replay it without yelling at me first then charging me thousands!!!
so getting a new air sensor would fix the problem?
thank you

just dont put that BOV back on & you shouldnt have any more problems
