Default 1997 chev 1500 pick-up I need some help with this

On 10-30-2011 I replaced the fuel pressure regulator, which greatly improved truck performance and gas millage. Flooding was causing engine mis-fire I am still getting trouble code # 172 &175. I am also getting two new codes #420 & 430. Can ya'll tell me what I need to check or replace to get rid of the two original trouble codes, and or if I did something wrong to cause the two new trouble codes? My auto mechanic skills have fallin off over the past few years and the complexity of the newer autos has greatly advanced.

172 and 175 are the engine is rich, and the others are cat sys eff. running the car with flooding can quickly take out the cat. or cats in your case. looks like you need cats, and go from there. hopefully you dont need to do the injector upgrade too.
