2008 Acura RL, ~143K miles. I was parked taking a call and my dash lit up. I found P0171 and AWD77 codes on the message center. The dash light went out and have not come back on, but my mileage is down ~30%. The car runs pretty normally (no rough idle etc)

I checked the intake and all seems in good shape (no cracks, splits etc) so I am suspecting o2 sensors. I've looked through various internet sites and can't seems to find answers to my questions.

My question's are:
1) Where in the heck are the o2 sensors located on the RL
2) How many are there?
3) Which are called what (banks and primary/secondary)?
4) Where is the MAF (or MAP) sensor and can it be cleaned?

Pictures or diagrams are good ;-). Thanks in advance.

Search is your friend... this gives more information around the issue even though it is for RDX I believe...
