Check engine light
My wife's 2011 SL63 just had it's check engine light turn on. I had the codes ran at a local parts store and there was 6 codes. It was basically just 2 repeating codes:
P0171 - Bank 1 system too lean
P2187 - System too lean at idle: Bank 1
Any advice on what it could be and if it's an easy fix? I'll probably take it to the dealer, but it's always a arm and a leg there.

All the reading I have done implies it might be MAF, intake manifold or some vacuum tubes.
I might end up just taking it to the dealer. I've got Fidelity Platinum extended warranty, so I'm hoping whatever it is they will cover it.
