Hi guys. Mechanic here. Yes, it will work.

OTOH you are a bad person if you do it. Instead, you should fix the Fiero. If you fix the Fiero, the gods will bless you. If you cannibalize the Fiero to revive a Beretta, you will face eternal damnation.

If you want to, you could always put the 2.8 in the Beretta to get a basic car going right away and then get a small-block conversion for the Fiero. That would not upset the car gods so much.

How do you adjust idler to 1985 pontiac fiero?

There is no idler pulley on this year Fiero so you must mean Idle Speed. It is most likely that if the idle is high and it wont slow down automatically, 1500 or so, that you have a cracked EGR pipe between the intake and the EGR valve. There are replacements available on line from companies like "The Fiero Store"
