Stalling idle issue

To start off i have 3 codes

-p0051
-p0138
-p0462

Now ive looked on multiple treads but am finding mixed fixes. So the car starts fine when cold, but after about 2 minutes in starts to run rough and ends up stalling. After it warms up, it wont stay turned on and constantly stalls without giving it some throttle. Could all of this be caused by the two o2 sensor codes? or is there something else i need to check. I've seen people mention MAF, intake gaskets, Throttle body, idle relearn, and injectors. I tried to perform the idle relearn but the car just dies so I couldn't do the process. any help is appreciated, thanks!

Unplug the MAF and check whether it runs without it. It should; if it indeed does, your MAF is bad.

Just unplugged it, ran the exact same. only went intro limp and turned on tcs and slip lights.
OEM MAF the way to go?

just cleaned the maf to see what that would do, and it stopped lol. I guess time will tell. none of the o2 codes would cause something like this?

Buy the Hitachi MAF from Rockauto and keep it in the car. You'll need it - even if only to prove/disprove that your current MAF is OK.
