Quoted from slochar:chuckwurt do you have the proper flipper bats on your game - those look like the fatter Bally profile ones - one of the symptoms - flipper hop!
Otherwise pull that guide fill it and drill it then reinstall. Flipper hop is eminently fixable relatively easily.
Sometimes you have to move the flipper mech in the PF which is the most involved it'll end up being, but flipper hop sucks and is worth pursuing fixes.
Mine had the same problem. It is an easy fix. Remove all of parts around your flipper so you have easy access.
1) Get a piece of plastic 1/8" thick. A cheap paint stir stick will work.
2) Drill a hole in the plastic same diameter of the holes in the play field (.093" I think ). You want the hole to be near the edge of the plastic as you do not want a lot of excess material getting in your way.
3) Place the flipper end of the ball guide into the hole you drilled in the plastic. Now slide the plastic to a point to where the ball guide will be located just a little bit above where it meets the flipper. You want the ball just barely dropping off onto the flipper so you get a straight run from the guide to the flipper and on down to the flipper tip.
4) Tape the plastic into position.
5) Remove the guide from the hole you drilled in the plastic.
6) Drill a new hole in your play field at the position of the hole in your plastic (What you made is a drill guide ).
7) Remove the plastic that you taped down.
Install the flipper end of the guide into the new hole you drilled. Your hop is now no more.
Do you need to use the plastic? No. Not really. But the plastic lets you slide the guide into the proper position without having to resort to bending the guide. Your hole will be dead on proper placement every time.
