I think I know what you mean and mine does this from time to time. (2001 S, 6 speed.)

I'd say it's more like an air "burping" or "gulping" sound, which could be described as a muted/muffled/soft popping or knocking.

I've always assumed it was just some normal intake noise -- never noticed any problem.
