Had issues with codes P0171, P0356, P0358, P2198.

What is your question?

I know what the codes are & gave had alot more codes I've fixed but the main problem is the P0171, & P2198 code cause the coilpacks are showing cause it's in Failsafe mode. But I replaced the O2 sensors except Bank2 #2 & it's good & checked the wires & PVC & vacumn leaks & the most common issues. I'm thinking maybe a stuck Catalytic? Please any help??
