Well, I might of spoke too soon. I drove 150miles without any CEL since cleaning the MAF & Inspecting all vacuum and PCV hoses last friday.
This morning 2 new CEL showed up with the same as before:

P0133 O2 Sensor Circuit Slow Response (Bank 1 Sensor 1)
P0171 System too Lean (Bank 1)
P1134 Oxygen Sensor Circuit - Transition Switch Time Ratio (Bank 1 - Sensor 1)

I'm bummed and running out of explanations...but the funny thing is that the car seems to run better with the code, it seems to pull harder.
