Throwing parts at a car tp fix never works

The code you have does not indicate a bad MAF sensor !
And the codes come in an ordee for a reason, usually the main problem is the first cause, and the other are caused by this problem.

Go to a good garage and have them diagnose it.

Edit:
I've just checked, and the problem for P1276 is "signal delay time for oxygen sensor ageing, bank2, above or below limits".
So
Check all the o2 sensor wiring and connections. Then change the o2 sensor left to right and right to left. Then erase the codes.
When the codes come back, if the code is still P1276, then it comes from somewhere else, can be an exhaust leak at the head, or a leak anywhere but in the intake that leads to more air in the exhaust.
If it comes back as P1275, then the O2 sensor might be the problem, wire, connection, oxydation... Check it.
