Whats wrong with my 1996 Protege, it idles great but dies when i push the gas

I would replace the fuel filter first. With the filter removed check the gasoline that is in the filter for water. If the gas has water in it add a water remover product "any brand" or alcohol. If the filter doesn't solve the problem the fuel pump may be functioning, weak. Replace the fuel pump, you can find step by step instruction here- http://www.ehow.com/how_6051838_change-pump-1991-mazda-protege.html. Mine is a 91 but the process is very similar.
