With apologies to Dukester for this slightly off-topic divergence, I think I've resolved the disagreement between 82-T/A [At Work] and myself.

...to be perfectly clear... no Fiero ever "came from the factory" with the distributor that has the star of David pattern. They all came with the one that looks like little points sticking up. But the "star of David" design is a NEWER design.

Sorry Todd, but it turns out you are absolutely wrong. According to information I've dug up, '84 dukes indeed "came from the factory" with the "newer" style distributor... which is what I've suspected all along.
I had to use the Wayback Machine, but I found a site Here with some pertinent information on Fieros. He apparently had an '85 duke. In his distributor rebuild section Here, the fella says something pretty interesting!

I’d replaced my old distributor with one of a better design. I’d thought that was a ‘new and improved’ design, but it turns out that it was the design that was used in ’84, which was replaced the next year with a cheaper, flimsier design. No wonder GM went with a distributorless ignition in ’87.

When I read that, I was inspired to do an online search for an '85 2.5 distributor, and bingo... the "older" style duke distributor.
So... what's it all mean? It means that '84 Fieros came from the factory with the "newer" style distributor. The '85-'86 dukes then came from the factory with the "older" style (probably because they were cheaper to make)... but because they were also flimsier/inferior, many (but not all) replacement distributors for the '85-'86 duke incorporated the superior aspects of the '84 distributor. (They're not exactly the same distributors.)

Todd, the "point" was that I wanted the truth of the matter to come out. Now that it has, we can find something else to disagree on.  [This message has been edited by Patrick (edited 02-24-2023).]

Bringing this back to the original topic...

I had earlier linked to a site Here that discussed Fiero tach filters. At that site was a link to a schematic.
Keep in mind that it's a schematic of a tach filter for a 2.8 V6... but would one for the duke necessarily be any different? 
[EDIT] The more I dig, the more I'm finding out. Here's something interesting from Rodney Dickman's tach filter page...

A direct replacement on ALL years of the 2.8 V6 and the 84-86 2.5 L4 Fiero motor.

Looks like you can just wire one of Rodney's tach filters in and you're all set! If in doubt, contact Rodney and explain the situation. He's a knowledgeable guy.[This message has been edited by Patrick (edited 02-24-2023).]

I don't mind the off topic divergences at all. Its good information and now its there for everyone to have.
While that's good information to build a tach filter. 82-T/A's documentation shows that my assumption this was related to the tach was wrong. The tach filter is on the white wire after the ICM. This doodad is on the 12V purple and black wire before the ICM. I might just give it the ole leroy jenkins treatment and throw something on there to see if it helps. Start at 47uF and go from there.

I don't think this is the silver bullet you think it is... but I will admit when I'm wrong, and you've converted me. I believe you, and I apologize! Hahah... damn you!
I would like some additional information on this, because I really want to correct my webpage with some better information. I do think the "new and improved" one that we now think came with the 84 is still a better design, and I'd like to emphasize that. But just want to be clear on it.

As long you and her have the patience to deal with these quirks. Go for it. She will never forget it.
Just teach her good defensive driving. Stay away from everyone always.
As an added bonus the iron dukes guarantees[i] that she will never get a speeding ticket. |

**** **** **** !!!
I just bought another Fiero... damnit... haha... what the hell is wrong with me.
Here it is in all its glory... now I need to bring cash and make the 3 hour trip...
I'm such an idiot... lol. I literally already have a Fiero that's not running.
But truth be told, this is for my daughter. I swear, when I told my wife this, I was not making it up. I had this car up on the screen, feverishly looking up distributors so I could prove Patrick wrong (just kidding), and I had it on the screen. My daughter came in and was like... Ooooh!!! I like that car, and then commented on the pop-up headlights, and how she liked that it was small. So I told her... would you like this for your first car? You'll have to earn it, but we can work on it together... and of course she said yes.
So I put in a low-ball offer of $4,000... but told the owner that I'd had many Fieros in the past. And he accepted while thinking about it overnight.
Geeze Todd...

What a lovely little ride 82-T/A! I'm sure you daughter is going to love it. Lots of a good bonding to be had over these funny little buggers.
Always make sure to stress defensive driving. When you are in one of these cars, every thing else on the road is the enemy. Its better arrive alive driving like a grandma away from everyone.

Thank you... absolutely. My wife is really pissed because she thinks the care is insanely unsafe and that she's going to get T-Boned by someone in a "Tampa truck" (one of those huge Ford F-250 pickups with the lift kit). I told her, it's really no more unsafe than any other car, but she might be right, and I am a little concerned. I do know that being in a small car is often safer than being in a big car because you can get away from stuff and better avoid things.
But, we'll see... I'm making arrangements to pick it up next weekend.

Its a justified fear.
Do remember this is one of the safest non airbag cars ever built. Stronger than strong subframe. But those stupid trucks tend to go up and over these cars.
My dad taught me to drive like everyone is out to get me. He mercilessly beat that notion into my head to stay away from everyone. Saved my bacon more times than I can count now. If you daughter is mature and gets the message, I wouldn't be concerned about any danger.
Plus she will never end up with a drug addiction, because the Fiero parts will make sure she can't afford any 😂.
We welcome her to the Fiero Family------------------
My girlfriend said she's is gonna leave me if I buy one more car, I sure am gonna miss her.

Every Fiero 2.5/2.8 engine (except the the distributorless '87-'88 L4) apparently requires a tach filter. I wouldn't completely dismiss the idea that this "doodad" isn't a tach filter for the '84... because if it isn't, then what is and/or where is the tach filter on an '84?

There was never any disagreement on that. For both the 2.5 and 2.8 engines, the "newer" style distributor (which in reality was the older original style) is superior.
