1999 Chevy Silverado 6 cyl Two Wheel Drive Automatic

Okay guys I'm back with the same problem. Here is what I have done since Aug. 2008 I have replaced the MAF sensor, air filter, knock sensor, fuel pump, coil, tps, fuel filter, distributor cap and rotor. But guess what I am still having the same codes in this order P0327,P0171, and P0174. I am going crazy. Now what do I do?????????????????????????
