P0172B Bank 1 System too rich
I know I've been asking LOTS of questions! 
My bad, this dang car keeps giving me problems. OK, so I just replaced the EGR valve (This was after a stuck EGR valve code I didn't just replace it) so this new one pops up named P0172B Bank 1 System too rich. I was told it might have something to do with me 02 sensor - thoughts?
