Need help please on 2007 Ford Mustang

I have a 07 mustang v6 the scanner gives me these codes p0175,and p2195. Both have to do with the o2 sensors which I have replaced all. I also replaced the MAF sensor too any ideas on what it could be. Any advice would be helpful thank you.

These are codes that indicate that your engine is running too rich. P0175 indicates bank 2, P2195 indicates bank 1. A MAF would not cause this. Oxygen sensor failure would not cause this. The best thing to have done would be to have had a proper engine performance diagnosis done, rather than drop all that money for sensors you did not need! You could have a fuel pressure regulator issue, a PCV system issue, a vacuum leak, an EGR system issue, a base engine issue, exhaust manifold leak issue, a fuel injector (or injectors) stuck open dumping fuel.... You'll have some testing to do before doing any more repairs. Good luck!
