Try some sea foam and see if any cracks show up . If you can get live data we can see were the problem is.

Also when I had my codes read this morning,, it said 1 of four? but that was the only thing showing? I'm doing the gas peddle thing to reset the codes, but now thinking it's not clearing all of them??

Suck a little seafoam into the intake via the evap port with the motor running. If the engine compartment fills up with smoke, you have an exhaust manifold leak.

That said, I have no idea if a leaky exhaust manifold is sufficient to cause an O2 sensor code. Mine leaks like a sieve, but other than the puff puff puff sound I now hear constantly since I did the above myself, it's not causing any apparent trouble.

The defouler wont fix it.
Go to autozone they will read for free ,need to know the numbers between the upper o2 sensor and lower o2 sensor to see why its not working .

Check your wiring, clean contacts, add dielectric grease, and do that for every connection you can find
