You certainly can use to go in this way, but it's a somewhat informal usage. Dictionary.com definition 46

to go: Informal. to say; declare (usually used in speech)
I asked the clerk for my receipt, and he goes, “You don't need it.”

Many people who think the above example is excessively informal / uneducated will nevertheless accept as the saying goes because they've heard it so often (besides which, as the saying says sounds silly). But it's essentially the same usage.


Additionally, as StoneyB says, to go can also have the sense to follow a course. I don't know what might have been written about OP's particular "suggestion" earlier, but it's possible the usage can also be seen as a shortened version of ...that early suggestion went on to explain, for example.
