Ugh! Steves emissions is out of business! Now where do I go to get emissions on my 40? Anyone know where they are mostly concerned with what comes out of the tailpipe instead of under the hood? It runs perfect, just lacks a couple of details under the hood!:rant:

I don't have a recommendation but looks like the list of "independent" emissions testing businesses is getting pretty small based on this:

There's a really small shop that does 81 and earlier tail pipe tests on the corner of Federal and 37th. I used to live down the street and went there a couple of times.

37th and Federal is still there, but they will require yo to have an air pump.

Hmm, must depend on the day I guess. When I went there, I had no problem and my 40 is completely desmogged with a header.

yeah, but yours is a '73, which might be old enough to be off their radar.

To the OP, I just took mine to a standard AirCareCO place, and having the smog pump hooked up, air rail installed, and vacuum lines running hither and thither, they didn't take a second look. But on closer inspection, they would have found out that one of my distributor ports was plugged, and several ports on my '78 carb were plugged, since I have no use for them on a '77. I guess my point is that if it looks like it's all there at first blush, you'll probably get through. However, that was almost 7 years ago, and maybe they're more strict now.

Mine passed at CO air Care a couple of years ago with nothing on it. Maybe it was the technicians first day (or last). I have a box of emissions stuff that was donated to me by a guy on MUD. I think I might as well quit playing the game and just put the parts on and not worry about it . Luckily the 77 doesn't have a whole lot of vacuum madness like the later years.

Bummer! They used to have the coolest collection of hotwheels and matchboxes!

Update:
In case anyone is interested, I called the emissions ref and was informed if you live in the enhanced emissions area I could pass my 1977 fj40 2f with header and no EGR as long as I installed the air injection system.
So I promptly spent the next couple of hours installing the AI system and went to the Air Care Colorado and passed. Still runs good. I can't tell much of a difference.
Hopefully you wont hear any more of my whining about emissions:blah:

So how did you install air injection with a header in just a couple hours? That should require welding air lines to the header, etc. You must be fast if you did all that in a couple hours.

Also, as far as passing with a header, that should be no issue, there's nothing in the rules that says you can't run a header, it just says you have to have all the emissions junk that it came with, and headers usually eliminate some of that. But the ref allowing a pass with the EGR not being there confuses me. It's likely the flunkys at the test lanes wouldn't catch that it was missing, but the ref was asked the specific question. I can't see how it would be ok not to have EGR installed if the truck came with it originally.

The 2f has AI nozzle ports in the head. Mine had plugs from the PO. So it was a matter of remove and re-install an air injection rail, smog pump,etc.
Ref merely stated the tech will look for AI and pump if stated on the hood decal and the techs wont look for EGR. He did state however: "All stock emission components originally equipped are required at a federal level".
As far as header goes the stock exhaust manifold has a port for EGR. My header does not have one.

aah, been a loooong time since I've had a 2F, don't remember that. Strange, the ref effectively said you need the EGR, but they'll never notice it missing. Wouldn't have expected that.

My experience was similar...my 1976 FJ40 has a rail and air pump,
but no EGR and no carb. preheat due to the header. Last month at
the Boulder Air Care, the poor gal who works there (seems like a
miserable job...) spent a few minutes peering under the hood, but
apparently was okay with what she saw as I passed without a problem.

In '04 when I was getting my '78 FJ45 imported and passed smog here in Colorado, I had to take it to their headquarters. The guy that was 2nd in command of the whole AIR program (PhD Chemist) took an interest in my truck and personally tested it. Guess it is a pretty cool looking truck. Anyway, he explained why EGR is not necessary at our elevation in a normally aspirated vehicle.

EGR is to prevent combustion temps from reaching the point where excess NxOx is created. We don't have enough air up here to reach that point, therefore there is no need to dilute the air/fuel mixture with spent exhaust to keep the temps down.
