90 Geo Storm ROugh Idling

I have a 1990 Geo Storm that has started rough idling. Someone suggested that I spray some carburator cleaner directly into the carburator to rid it of any possible gunk that might be in there. Thing is....and without trying to seem too much of a dunce....where is the carburator on a 1990 Geo Storm ? I looked in the Owner's Manual and it is no help at all. With an old car that I had I remember removing the 'pizza' size air filter and it was under there. My Geo is of course newer and its not made that way under the hood. Any suggestions ?

Thanks

Sounds like you have vac hose problems...Check vac hose routing chart I think on under side of hood or on radiator support..then trace your vac hoses to see if one may be loose of broken
