Re: I Keep Getting CEL On My EM1
could be low fuel pressure or clogging injectors, or could be an exhaust leak before the o2 sensor, these are guesstimates to get you on the right track

P0171 is a pretty common code. In tracking a few of these down, it's almost always a vacuum leak. It can be caused by inadequate fuel pressure but it's less common. I have found one of the easiest things to do is listen for an air leak with the car running.

Sounds like a LAZY o2 sensor.
Replace the o2. 7 times outa 10 the o2 sensor is Lazy with this code.
Best of Luck
