Michael, I have 3 GM OEM gaskets.  They are graphite coated and I believe they have a wire mesh inside them.  Email, text or PM me your address again and one will be in the mail in the morning.

1.    The ones that learn by reading.
2.    The few who learn by observation.
3.    The rest of them have to pee on the electric fence and find out for themselves.    Will Rogers

I ordered 2 from the Fiero Store.  I feel badly about you spending money to mail me parts.

I'm wondering of the problem could be that I have a heat-coated EGR mount plate.  I put the question to TFS.  I believe they discontinued selling this product, and this could be the reason.

It couldn't cost more than 2 Forever Stamps to mail it.

TFS says there have been no such issues with the heat-coated EGR mount plate.  They suggested that I find out why the exhaust is getting so hot.  Surely, that much heat would cause problems for other gaskets, as well, such as the one on the top of the mount plate.

The only real complaint I have about the engine is that the MPG is low.  The flooding/burning oil should be a separate issue, but perhaps not.

The gaskets arrived today.  They are purple, and seem to be made of some sort of metal.  I put one in, and put the Fiero back together.  It fired right up, after sitting for 12 days.  No smoke, nothing.  It just fired right up.  I went for a 30-minute drive.  No leaks, and it sounds right.

I have the new detent cable, and tried to replace it, but that didn't go well.  I maybe should've released the end off the throttle, but I couldn't get the end out of the transmission.  It works--it just looks badly.

What could happen while the lower intake is off that would cause oil and fuel to mix?  Gasket?  Mechanical?

What happens if I drive my Fiero in its current condition?

   If the smoke cleared do not worry unless it appears again. if the Detent is not adj. Correctly It Can Cause Trouble with the clutch Plates as they don't Shift with the lock up force they need and then they Wear. If It's as Simple as most GM cars It's Easy. If it's all hooked up Push in the Cable adj. lock and rotate the throttle to wide open at the Injector not the pedal, then let go the lock then the throttle. that should be it.  Of course the Fiero is likely diff.

I'm worried about whatever is causing the oil to get black, and the oil to be burned.

Engine oil doesn't stay clear.  It quickly picks up blowby contamination from the engine and starts turning dark.

I lost a quart of oil in less than 1,000 miles.  It's visibly burning oil.

Perhaps the oil does get dark, but I've run new engines through several oil changes, and still had almost clear oil.

I learned something new yesterday: the injectors need to match.  If you have a "matched" set of injectors that aren't identical, your ECU will have problems figuring things out.  Apparently, the ECU knows something about the injectors, liking some types, but not other types.

Hmmm.  Apparently, there are still vacuum issues.  There is supposed to be a pressure difference going to the vapor cannister.

I took the Fiero out for a drive, today.  There were several oddities:
1.  Rather than the usual 16 MPG, I got about 28 (8 gallons in 237 miles) at 80 MPH.
2. The engine kept cutting out on me, as if it wasn't getting fuel.  Usually, this was just a pause, but once I lost power for several seconds, and another time, almost didn't get it re-started.
3.  The AC never got more than cool.
4. The engine ran almost at the red for temp, for the first tank of fuel, which got me about 22MPG, then for the 28MPG tank, it ran about halfway.  I noticed with the first tank that the engine ran hotter at 70+ MPH than at 50 MPH.
5. When downshifting, it went to second gear, which is about 6K RPM.  Adjustment needed.

I was thinking that maybe the engine got heat-soaked.  I will say that above 80 MPH, the engine comes to life.

Changing injectors.  Not liking the Accel brand.
