when to replace o2's and a/f gauge question
just wondering when i should get some new o2 sensors for my car. car has about 47000 miles on it. dont know how to tell when they are goin or what. also, with the air fuel gauge taped into my driver side sensor, would that effect how the car would run and effect anything or should it be ok? thanks guys.. o yeah no codes except on cold days i thwor a heater code on bank 1, but i have headers

Hey man, i have 70k on my LT1, and i *think* i need to replace my 02 sensors. My A/F gauge will be aight like stoich/rich, then shoot all the way down to lean when im just idle, does urs do this?? or what. Also, mine is also tapped into the drivers side and i have Jet-Hot longtubes, orypipe through borla. I have a ses code (prolly a few) becuase of no smog pump, no cats, no this, no that lol. I have to get it checked out and see whats up. Like i said, im not sure if i have to replace mine or not, but it studders at low rpm and i hear this is a sign. Good Luck, Dave.

Bosch used to say 50,000 miles max and last year dropped it down to like 30,000 for the older they get the slower they get, smog gas use and being the front O2s cost about half of what the rears are I would change both fronts since newer ones produce truer values.
