Out of curiosity, what is your highway RPM at 75 MPH?
I have to fix the tach first. It read about twice the actual RPM. Or I could take my scanner on drive and see what it says.

Wrong VSS?

Or possibly a bad tach. The tach in my yellow car read 2x when I first got it. I put in another one and it's perfect. I have another one to try in this car.
Edit: The scanner reads the correct RPM, so the VSS must be OK. I can pretty much tell by the sound what the real RPM is, especially at idle speed.

IIRC, this was originally an L4.  Was the tach changed with the swap?

Yes all gauges replaced with Formula-style gauges.

If the tach reads exacly 2x, then the RPM at 75 MPH is 2300.

Today I replaced the tach with the other one that I had. Bingo! It reads correctly now.
But a new problem has cropped up. Every time I start the car, the SES light comes on a few seconds later. So I hooked up my scanner to see what the problem could be. It said "EGR pentle is not positioned correctly". I'll get another one soon. The one that's on there looks very old and rusty.

Isn't it amazing, how new issues crop up?  Clearly, this is unrelated.

I put a new EGR in today -- no SES light. And it adds a little bling to the engine compartment. It was expensive -- $150 (Autozone Duralast brand). Rock Auto has them MUCH cheaper, but I didn't want to wait.
Old EGR:

New EGR, on the engine:

It's prettier than the old one would be even if not rusted.

Yes, better design.  What goes in that hole in the shield?

No idea. It might have been something required for the Buick the engine came out of, but not for a Fiero.

That adapter/mount block under the EGR valve could use an Evaporust bath, just so it matches the valve.

Today I had some time to work on the interior of "White Lightning" and it's almost done. Here are some pictures.
I liked the burl wood that Lee had put on the various bezels in the car, but some of it was in bad shape, so I bought new burl appliques.

The "Fiero" floor mat you see is from Rock Auto. I couldn't get toe old burl wood off the dash bezel, so I started with another one I found in the barn. Also, the shift bezel was in bad shape, so I bought another one from Ebay

Here is a picture of the interior before any work:

It was pretty yucky, with plenty of mold and other crud on surfaces.

I managed to get one of my new seat covers on. I may be able to do the other tomorrow.

Notice how nice the center console and glove box door look. Before, they were warped, as in this picture:

Actually, the hardest part to fix was the shift surround, which doesn't look too bad in the above picture. The soft plastic was separated from the harad plastic, as usual, and repairs had been attempted with several kinds of glue, and even duct tape. I had to clean all that junk off and repair it properly with the proper glue:


All that was needed to restore the door panels, besides new burl wood, was cleaning (and cleaning and CLEANING!), because...


The door panels used to look like this:


Little touches include a new horn button, because the old one was cut from an emblem that was too big, and didn't look too good.


The Fiero Store had an emblem that was just the right size for the new horn button:


I got some for the new wheels, too, to use instead of the wheel logos.


And besides all this, I've been driving the car around with some of that Thermocure in it (and plain water). The directions say to drive it at least 3 hours and up to several days with the stuff in.

Very nice!

Interested in how the Thermocure works out.

I had a black hand items in my brown interior Fiero, also.

That new sest cover looks awesome!

Impressive work Pat!
How do you like having the Automatic transmission? My '88 project car has the same trans and I'm just not up for all the work to put in a manual trans.
