If the vinyl tiles are loose they need to come up...but if they are well and truly stuck then make sure you wash them with a degreaser like sugar soap and then once dry.. prime with neat bal bond sbr and tile within 24hrs of priming......if you are just putting a yinyl sheet type flooring down then self level over them and lay on top of this once dry...
