Sounds like you have a bad opto... Mine had the same issue, the opto on the right under the vengeance was bad on mine. The good news is that Patrick at stern will send you new opto's no problem! the bad news is that the right opto is a PITA to get to. I would double check the connections under the playfield where the optos plug in (reseat them) maybe you will get lucky.
Quoted from Gorgar1:Mine also did that but I just adjusted the spring so it's tighter and holds the target in place
Forgot to mention I also tried this (see pic) before replacing the opto but it didn't help my machine.
The little board the opto attaches to on my machine had a bad connection causing it to randomly trigger. If I put the game in switch test mode the opto would randomly trigger even when I wasn't touching the machine.. I believe it was switch #33
