fast idle still 93 t-bird

if you gave it gas, then no. Did it start before?

Should only do that with engine already at operating temp.

You might have to fiddle with the accel to get it to start, first try just a little pressure on pedal, then to floor then pump it, once engine smooths out, see if it idles very slow, or dies. If so, then the IAC is either bad... or there is another problem but not a vacuum leak.
