Yes, I had this problem with mine, too. I was able to fix it by bending the rollover wire almost straight and then making a it much smaller and closer to the pin that fires out. The reason it misses so much of the time is that the when the ball goes down the outlane slowly (which is most of the time) it causes the solenoid to fire too soon. It used to miss about half the time, or maybe even slightly more. Since I fixed it about 4 months ago, it has only missed twice that I can remember. If the ball comes screaming down the outlane it won't have enough time to fire, but this rarely happens. It's really not a problem at all anymore.
