There is no idler pulley on this year Fiero so you must mean Idle Speed.
It is most likely that if the idle is high and it wont slow down automatically, 1500 or so, that you have a cracked EGR pipe between the intake and the EGR valve.
There are replacements available on line from companies like "The Fiero Store"
