Quick o2 sensor question, P0153

Re: Quick o2 sensor question, P0153
My programming has nothing to do with the front o2 sensors and it would not affect them in any way. I disabled the rear o2 codes like you asked, and you will not be getting any codes from those. Since you mentioned the problem started only after removing the cats, perhaps you melted some wire during the welding? I would double check the wiring going to the sensor.

WTF i had a huge post in here and i got deleted? why?
in response to the above topics im still stumped, after numerous shops and even 2 GM dealers, the official word is that the sensors are not being contaminated and that the light is not false(meaning that the O2 sensors really reads bads bad enough to throw that light), somehow the exhaust modification caused this problem or the programming...........
Had these places checked everything, fuel pressure, ignition, injectors, you name it, even swapped MAF.......what is going on here, no one seems to have this problem but me

Did you ever check the wiring? Is it possible you have a high voltage wire, like a plug wire too close to the O2 sensor wiring? It can induce spurious voltage transients in the sensor signal. Are you using extensions? Are you sure they are "healthy"?

Re: Quick o2 sensor question, P0153
I know i look like an idiot here, but i had a HUGE post made after that guy had the question about the y-pipe that answered many posts related to my topic and responded to his question. I know your probably thinking "that idiot probably closed IE before it was submitted or something..." but I admin a set of forums like these(only smaller, maybe 100 users), so I'am quite familiar with system, maybe it was server error or something, but i saw the post there with my own eyes! either way, no big deal.....sorry for the rant.
But thanx for responding to my post again. I have checked the wiring and connections and had a GM dealer double check EVERY other possible alternative for me, I'am not using any o2 extensions, all stock unmodified wiring............This was suggested many posts ago and I've since double checked numerous times. I'am open to ANY other suggestions though as this is really getting annoying. This should not be happening......
