Many years ago someone failed the smog test because where they had their car inspected saw Holley on the TB and thought it was after market. Most of the people working at these places are just there for the paycheck and to say that their knowledge on cars is limited is the understatement of the century. As long as you can make it look stock you will get away with it as they will have no clue to what goes on a Fiero let alone any car.

I would rather ground out the EGR Solenoid, block the EGR tube to the plenum and call it a day. |

Our EGR systems are electro/pneumatic. It consists of the EGR solenoid and a separate EGR valve. Valves are available, but the solenoids are no longer manufactured. The only source is from a parts car or if you're lucky, you might find a high dollar NOS solenoid.
Converting to the digital EGR eliminates the pneumatic part of our smog control and replaces it with ECM programming. The 7730 ECM controls the EGR valve. The 7730 also manages the engine much better with a faster response to the engine sensors.
You could do as Notorio suggests and dirty it up a bit. But that probably wouldn't help on our current production run. They have Georgia Fiero engraved into them.
Or explain the shininess with "The old one kept blowing gaskets so I had to get a new one."

with the new tests on our old cars in california they should just plug in odb or just throw the sniffer in the tail pipe if it blows clean it should pass.

If this is FOR SURE true (and it probably is), you can be the guinea pig, swap on the digital EGR, and then go fail a smog check. Go to a referee, tell them the part is not available. They will make you contact the Parts Locater Service. If the PLS cannot find you a solenoid, they will write you an exemption for your fix. I've not successfully executed this - I haven't tried - but it's an increasingly available option for '80s cars!

You are trying to apply Logic to government. Nothing could be more hopeless an endeavor in the State of California. At some level this is a government jobs protection measure.
As far as EGR availability, what am I missing? Just consulting Rock Auto for an 88 at least there are two different suppliers to choose from ...

EGR *valve* (driver's side, on exhaust) is available. The EGR *solenoid* (passenger side, up by the temperature senders) is unobtanium as new. (There is a guy in Fresno or someplace that refurbs 'em, though, so they can still be had.)

LOL, I used to be able to read and comprehend. 
For those of us who have been oblivious to the existence of the solenoid, here's a little post from 2013 with a picture of it and a procedure to repair. How I repaired my EGR Solenoid and eliminated my Code 32
I guess this is another item we should all be pulling when visiting the scrap yards ...

The Celebrity, or one of the other FWD GM cars with the 2.8, used a similar solenoid. The difference, as I understand it, is that the tube on the end (the useless one, that goes to the firewall) is replaced by a block of foam, as a filter. I've seen pictures. It looks a bit different, but is supposed to function the same.

This one from a 89 firebird 2.8l looks really dead on

To Notorio and CLIFF- this LINKED thread on repairing an EGR solenoid should be in the "Faqs and Howtos" section........
Also, Thank you to Timepilot who posted that repair info- He came back numerous times with updates reporting that the fix actually continuing to work for over a year.
