It does act very odd. I wonder if the factory installed clutch pedal return spring (which was subsequently recommended to be removed) is responsible for the "bounce".
But I still think the root problem is air in the hydraulics.

If you installed a slave with a single seal, it's crap, and is possibly the source of the problem.[This message has been edited by Patrick (edited 07-20-2021).]

This is the slave cylinder changed in 2016 :

I don't know if it's a good slave cylinder.
I've bought my fiero in 2017, this was the previous owner has changed this part (i've seen the invoice from fierostore)[This message has been edited by zobari (edited 07-20-2021).]

At the Fiero Store site it states... "These units are made to original GM specifications." If that's the case, then I suspect the slave cylinder only has one seal, which would definitely be more prone to sucking air into the system than the double seal slave that Rodney Dickman sells.[This message has been edited by Patrick (edited 07-20-2021).]

I'm thinking that the problem lies at the front end. The way the pedal free-swings says it's just hanging there. There's no resistance from the master cylinder piston and spring until it reaches the bottom of the bore. I think the master cylinder piston is stuck. It couldn't be that the pushrod has detached and the small spring inside the master cylinder would still give some resistance to the pedal.

I will buy the the clutch master and slave cylinder from Rodney dickman and then I will bleed and I think the problem will solved...

Not that it's a bad idea to buy a clutch slave and master from Rodney (as they're both great quality), but why don't you try just bleeding the system first before making any changes to it? See what happens! If nothing else, it's good practice.  [This message has been edited by Patrick (edited 07-20-2021).]

Sound to me like you have this problem going on 🧐 this happened on my 86 gt 2.8 4 speed when I bought from the previous owner he thought it was the slave cylinder or master well changed both out and come to find out I still couldn’t go into gear but had nice pressure at the pedal and that 1-1/2 of the slave rod movement. This was when I was like the clutch is gone let’s drop the cradle and see what happened soon as I had the trans separated from the motor the pressure plate was visible. Removed that and boom this spring fell on the ground 🤷♂️. That’s when it was time to install new clutch and get the flywheel resurfaced put all back together fiero 2.8 was driving and good to go

Even if the pushrod were removed from the slave cylinder, there would be pressure holding the clutch pedal at the top of its travel. It wouldn't let the pedal free swing the way it does. I think the problem is in that area, not at the slave or transmission. It may even be that the clip holding the master cylinder pushrod came off and the pushrod slipped off the pedal. None of this has apparently been checked out.
Do a visual inspection of the clutch pedal and the pushrod that attaches it to the master cylinder to be they are still attached.

I would think that the OP would've done that already (and found no evidence of detachment to report)... but yes, I suppose I shouldn't make any assumptions![This message has been edited by Patrick (edited 07-21-2021).]

I saw the tool in the floor under the pedal is why I thought of that.
