Probably better placed in the C5 Tech section for future reference.
Do you by any chance have an after market air intake system? If so, check every clamped connection from the throttle body down to the filter assembly. That's the most common source of leaks.
I had one that bugged me for days after I initially installed a "Blackwing" and after market rigid silicone coupler between the throttle body and air bridge. I had intermittent lean codes as well.
It turned out there was a pucker of the rigid silicone couple at the very bottom of the throttle body connection. It was impossible to see without a mirror. It allowed just enough leakage to cause the codes.
