My check engine light came on today on the way home. Pulled the codes with my Snap-on brick. Came back with P0134, bank 1 sensor 1.

No where in Alldata or anything that I have access to does it tell me which side of the motor bank 1 is. So, which 02 is bank 1, sensor 1? Front of the car in the manifold?

That should be your first O2 sensor, the one on the rear manifold. Check for a vacuum leak first, or a exhaust leak.
