Filled up today.  Pushed in 3.7 gallons.  Pump first stopped around 3.5 gallons, but thought that wasn't enough.  So 108.4 miles divided by 3.7 gives 29.30 MPG.  That's after filling up on the way back somewhere between Washington and Elberton, two days of sitting, and a work day commute.

When does your book about doing the change-over come out?

Write it in the 'see Spot run' form so I can understand it.

That's very good; considering your 'normal' driving ;-)

So, the rebuilt 2.8 is now in the car. All is hooked up. It runs, at about 3000 rpm. I have checked for vaccume leaks, grounds, sensors, switches. When I placed this into service, I replaced all intake gaskets and orings. Used my throttle body as I knew it to be good. I am running 7730 ecm with a knock sensor. I have driven the car about 70 miles and gas milage is about 10 miles per gallon.

Try removing the rubber intake duct from the throttle body. Place your thumb over the 3/8" hole that is in front of the throttle blade. The engine should stall, or nearly stall. If it doesn't slow down, you have a vacuum leak.

On Pennocks, he posted that it slowed it down, but didn't die.  He also mentioned that he replaced the injector orings.
I'm betting on orings or cracked egr tube.
Someone should place a long shot bet on the lim to head gaskets. Maybe one of them slipped.

Turns out that I have a warped upper intake manifold. Sad as its the one I painted and had all pretty looking. Car now runs and idles .

You could take the pretty one down to the shop and have them belt sand the faces true again.

Hey everyone,  I've never posted on this forum before, but I've owned Fiero's on and off since '89.  I'm neck deep in a 3.4/7730 swap and saw this thread.  I was wondering if you could tell me or point me in a direction to find out what code the chip from my 7730 has on it.  I picked it up online and it was supposedly from a 91 Corsica.  It says Delco, AUXX, 3823 on the silver tag.  TIA.
