O2 sensor contamination can cause it. An exhaust leak can cause it. A vacuum leak can cause a lean code, but not this code. Corroded or loose pins in the harness connector can also cause this code.
I haven't run into this code yet with longtubes, but that doesn't mean that others haven't had this problem. If everything else is actually right, and your tune is good, then killing the DTC is a viable option.
If your PCM isn't locked, I can help you do either one.

Usually when you only get 1 side, there is either a leak or a sensor issue.
Don't rule out a fuel or injector issue either.
I would Suggest you take roger up on his offer especially Since he is in AK and has the proper Equipment and know how to diagnose an Issue like this.
If you have a Log, Feel free to post it up. I have EFI live.
PLEASE DO NOT POST YOUR TUNE!!!

So I retorqued my header bolts to just rule out exhaust leaks.Went to clear my codes and found a new one. P1133, "undefined code" I'll get a data log up soon. How long should the log be?

After reading through many, many p1133 (Oxygen sensor insufficient switching) and p0133 threads on ls1tech a majority of people are just messing with the fuel trims to trick the sensor or are just tuning the code out permanently. :\
