Yup Mike, that is exactly what mine was doing, when it was not totally blocking the airflow it would start, and I am guessing the tip would spin inside there, because my motor ran so erratic, then on occasion I am guessing it got stuck while open, then the car would run fine.
It made it hard to diagnose my issue, because I never imagined that could happen.
I super-glued my tip back on as well, but in a few weeks it came loose again, so I discarded it, and the car ran fine, it really seemed like the tip made very little difference.
By the way, nice job cleaning the MAF, it looks a lot better!
