Persistent Mixture Control Codes

Hello guys. My MAF sensor (I assume was damaged) was replaced. I would stall out at stops have bad gas mileage slow acceleration etc. Now that I have replaced the sensor, I still experience some sputtering and even a stall. Another member on here has experienced the same issue as well. Is there anything else that could be causing a fuel mixture issue?

I had the same issue. It was my intake gaskets. My oil separator hose and crankcase vent hoses were cracked as well...
