Does the new pressure switch have the same settings as the old one, i.e. 30/50?
If it doesn't, you may have to reset the precharge in the pressure tank to 2 psi less than pump cutin pressure. This could be one reason for the sporadic flow.

Sounds like the pressure tank is waterlogged. Do you get air or water out of the schaeder valve?
