How many miles total, TK?
My car has never seemed to mind if I left it for a week or two at a time.
And I don't know about JH's history, but benz codes usually are dead on. O2 sensors can dramatically affect driveability AND ruin a cat if left alone, if that is the dtc I would replace the O2 sensor. That is why there are codes, otherwise you could drop a couple grand guessing at things. And why you would replace a MAF when you have a dtc for an O2 sensor is beyond my understanding.
At any rate, TK, the O2 sensors are pretty easy to change, just be sure to use the proper tool and use anti-seize on the threads, but be sure not to get any on the sensor itself. Since you have a dtc for a specific sensor it won't hurt to first inspect the wire to it to be sure it isn't damaged. If that all looks OK then swap out the sensor.
Take care and enjoy the ride,
