The symptoms you mention seem related to the IAC. The book says to swap and
check for vacuum leaks, check fuel pressure and for water, check for
sticking injectors
My guess would be vacuum leak, since the Fiero has those plastic vacuum
lines under the intake and to the sensors, you are probably getting a
faulty
reading from one of the sensors because of a leak. There is also that EGR
tube that tends to crack right under the intake manifold
An easy way to check is get some starting fluid and (sparingly) spray
different areas to see if the idle changes that is where you will find
your
leak. I know its backyard but it works!!
