Got my first CEL today after replacing my motor in March. It did not affect the way the car drove, no limp mode, sputter or anything. I drove to work with the light on the whole time. During lunchtime, I started the car, let it warm up and no CEL. Could this be a sign of an O2 sensor getting ready to crap out on me?
