John, this is the worst place where your airbox could break. The way it looks, you have unfavourable turbulence and possibly backflowing air right where the MAF seonsor is placed. You should repair the air duct there at the MAF sensor in a very round shape and very smooth. Or you might need this part new.
Regardless of possible leaks, I wouldn't be surprised that the wrong values were caused by a completely irritated MAF sensor.
or to say it positively, I'm convinced that after the repair your car could run like transformed.
I think you know the following anyway, but just to repeat it, I would remove the MAF sensor before you work at this point. And of course clean everything thoroughly afterwards so that nothing is sucked into the the engine.
