Default Re: Error Codes Help!!

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.
