Has anyone ever heard of such a 'FIX' or is this just wishful thinking? I forgot to say this is a 1997 Chevy PU 5.7. Hope someone can help.

1. There is no DTC that calls for O2 sensor replacement, doesn't exist, never did. You may have a DTC that detects a problem within the system but that's all. Did you have codes pulled by someone with experience or someone with a tool to do it? There is a difference.
2. No, there is no way to bypass the O2 sensors. Ask the person who gave you that info to please provide a manufacturers name or a link to me. I'd love to see it.
3. Bad news. Your truck doesn't have two O2 sensors it has four. Double you pleasure, double your fun.
Please don't think I'm being an ass but whoever is giving you this info appears to be clueless. My guess is you went to Autozone and had a minimum wage flunky plug in for free. Remember they're in the bussiness of selling parts not repairing cars (or trucks). If you supply me with the codes I can and will be of more service.
