A bad O2 would be it's own code, wouldn't it? P0300 seems to be a catch-all code for any time the ecu sees something weird.

My thoughts as well. All vitals are fine on the car. I just reset the code yet again. Next time if theres a next time I am going to do an exhaust leak test and potentially replace all exhaust gaskets.

I am thinking it may have something to do with my exhaust gaskets near the rear 02 sensor, the ones where the cat meets the y pipe. I have re-used them twice so it might just be a bad leak. haha

I reset the code on Monday and I have driven 100 miles so far...

I made it 700 on the first reset until it occurred again. I think you are right about the gaskets. I have long tube headers to AAM 2.5 true dual and HFCS so I think maybe the dealership loosed the connection past the HFC to re hang the exhaust and didnt tighten it all the way. For now though do the video game cheat to reset the code! https://www.youtube.com/watch?v=95WszTnphPI
