Question CEL code 172

So i was finally able to read my cel code. The code 172 indicated the right bank is running lean. It set the cel once and then went out. It was stored in the continoeus memory. I tested it twice in the koer mode before it read the code, though the cel didnt go on again. It did it twice a year for the past 3 years and went away. It never effected the driveability but now it is. The car is sluggish at times and hesitates. All the other sensors seem to be functioning properly. I wouldnt think it would be a vacuum leak since its so erratic. I think it may be the right 02 sensor failing finally. Also cleaned the MAF, though it wasnt really dirty. Any suggestions would be appreciated. Thanks!!!!!!
