Recently my check engine light came on. I went to Autozone and got them to pull the code and it came up as "P0174 - System too lean (Bank 2)"

Additionally, it has been surging occassionally at start up, but then idles fine. Also, the vehicle drives fine.

So, I have read several other posts about the IMG and EGR valve, and I kind of suspect an O2 sensor. Have any of you gotten this code before or have any ideas on how to fix it?
