Nope. The screws just hold it in place. They aren't used to ground it electrically.
I suppose you could have an intermittent module, but they really didn't cause much trouble compared to the stuff on newer cars. You might try a different ignition coil too.
Look too at the toothed reluctor wheel to see if it is cracked. I read a lot about that but I've never actually found one myself.
