I'm sure this has been addressed, but in my 04 Mach 1 I have a chirping sound when my foot is off the clutch. The moment I push the clutch in it stops. Car has a firewall cable adjuster and I believe a centerforce clutch
throwout bearing, try taking up more slack in the cable so that you have only 1/2 inch of pushing in the clutch petal from the top before the rpms climb (holding gas constant while driving at like 50mph)
The clutch petal should be firm at the top (no flop)... just be sure to leave enough so you are not engaging the clutch all the time

You probably have a throwout bearing going bad.
Squeaks when it is unloaded, but when pressure is applied it quits.
My daughter has an 04 Mach I and it had the same issue. Replacing the throwout bearing cured the problem squeak.
P.S. Spector, JFYI flowers have petals, cars have pedals.
