I did the major flex plate replacement job which included removing the trans from the engine and everything else... I was certainly worried that issues would come up, and they have..
I'm throwing codes on all the 02 Sensors and now I'm wondering why...

I left these pipes hanging inside my shed (while doing the fix, for almost a year), but exposed to the air (all 02's still intact) and could that have damaged the 02 sensors that were still attached to the pipes??

Are 02 sensors that lame?? can I fix them??
