Is this your first game? Have you cleaned the playfield? 2 weeks of constant playing Without wiping down Or cleaning the playfield should show some difference in the play ability. However, if it’s a considerable difference, then yea, may want to look into the coil stops as some have suggested.

Just trying to rule out the obvious. Some people may not clean their playfield after a few hundred games and it would be a considerable difference in play. Is that ok with you? SHEESH.

Here’s another thought, simple check which may lure in other technical a-holes, but Screw it - at least I’ll offer ideas and help. But, check the gap of your flipper(s) and Make sure they’re not dragging or getting caught on the playfield. I know some people have had that issue on newer sterns. I believe the simple check is being able to place a credit card smoothly through the gap.
