So as I am getting my x-fire detailed to sell it, my CEL light comes on. I pull the codes and it shows that I have a P0171 and P0410, I understand that these relate to air injection system and possibly MAF. Anyone have any idea as to how to approach this problem, thanks!

I checked my lines they all seem ok, I cleaned the RCM, the CEL light went off but after driving it awhile it popped back on

 

Nobody knows

 

Of course we know :

(P0171) FUEL SYSTEM 1/1 RICH CONTROL OVER LIMIT (AT IDLE)
(P0171) FUEL SYSTEM 1/1 RICH CONTROL OVER LIMIT (AT LOAD)
(P0171) FUEL SYSTEM 1/1 UNDERCORRECTION OF FUEL MIXTURE (OFF IDLE)

(P0410) SECONDARY AIR INJECTION SYSTEM.

I don't know about the P0171, but the P0410 normally means something is wrong with the air pump or the RCM relay/fuse that controls it.

To hazard a guess at the 171, maybe your air filter(s) is/are clogged ?
Or it could be the 1/1 Oxygen Sensor going bad:
Oxygen Sensor 1/1 Upstream At rear of left exhaust manifold.

 

Thanks so much!
