Lookin for some help here... I have searched the ORG but have not found this combination of issues. Here we go...

2000 Maxima AT-105K miles- all coils/plugs replaced 11 months ago. This month, SES came on, pulled P0174 from it. Changed out ALL four 02's. Then SES came on again but this time pulled P0430. I have seen some of the suggestions for fixing the P0430 code, but not following the 02 change-out.
Is this a code from the downstream 02 (after the front bank PRE-cat)? If my car had an ignition problem, would the upstream 02's pick it up, thus throwing different code? Does this code affect fuel economy? And is it fair to say the odds are I am going to have to replace the PRE-cat?
