Not a tech by no means and someone correct me if I am wrong, My trim values are staying around zero to plus 8 so it doesn't seem to be going to one exstream or the other as I would exspect in a close loop system trying to compensate for a bad feedback. I do industrial not automotive so if I am thinking about this wrong please correct me.

2006 has extra-fine orifices, especially prone to clogging.
There is a thread here in which a member tried to find alternative injectors for that motor, with some success, if I remember correctly.
That would be consistent with a couple of partially-clogged injects, for example; it tries going a little richer, but no improvement because now the cylinders with the clean injectors are burning too rich.
i'm not saying this is your problem, I'm saying with the age of that car, if it has the original injectors, it's bound to have a problem. No loss refreshing them, even if it doesn't solve the problem, and I suspect there's a good chance it will.

Well, just give a update. I ordered my oil cooler seals from GM Parts Direct which turns out isn't GM at all but a dealership. Three weeks later I got my seals and installed. This has fixed the oil leak but I have now lost comms with the TCM. I not sure what's going
on here. I had unhooked the battery when removing the cooler and it sat for 3 weeks disconnected, top plug on ECM was also disconnected, The fun continues.
