99 TA-Codes P172 & P172=running rich w/Macs and O2 sims

I have Mac mid lengths with the Hooker ORP setup. I am using O2 sims and now my car is getting the check engine light.
I pulled P175 and P172 left and right banks running rich.
It stalled on sat night but 20 minutes later it drove OK.

Any suggestions on how to fix this.
Thx
STEVE
