I just ripped up some one old one-piece vinyl flooring. Around the
edges, it was glued down.

There's residual glue when the flooring came up. I'm going to put
down self-stick 12x12 squares. I was just wondering if anyone knew if
the glue would cause any problems of if I should go get some glue
remover and take it down to the wood.

TIA

Leaving the glue equals doing a poor job. You need something like this:

If the wood is or gets damaged you may want to fill the holes and the
cracks and smooth the surface before tiling

PS: Why the xpost to architecture? There is nothing architectural in
vinil tiles...
