Fiero vacuum leak test

I did a vacuum leak test on the Fiero. This was achieved by starting it up, and holding your finger over the IAC port. The Fiero’s idle went down where it should be (950-1100 rpm) when I held my finger over the port. What does that mean? I have a F@#KING leak somewhere else in the vacuum line system. Sigh…
