Maybe it was the "This data is used to identify exceptionally-clean vehicles." that through me off. Would an 80 ever be considered "exceptionally-clean."

I you can pass the quick test on the rolling road you should be able to pass at the mobile stations. However, if your vehicle is not running clean it will flag it instead and force you to come in to the rolling road. If you're not sure, coast through.

My quick sorta unrelated story - back in 1999, El Paso County had emissions testing and it was time for me to register my 68 Camaro with a 427 big block. No appointment necessary and the tech actually leaned out my Holley carb so it just barely passed and then reset it right there in the bay. Took all of 20 minutes. Colorado certainly does not approach emission testing that way now!

Does anyone know what the maximum number of days prior to the registration due date an emission test is still considered valid? In other words, if I pass emissions in July and the registration is up the following January, for example, is the test still considered valid for that January registration?

I think it's up to a year in advance.

@Battlshp - I just posted some personal testing I've been working on in the past months to figure out emissions on the front range. Here's the thread that I just posted if you want to check it out, hopefully it will help with the '93.


Did you or a mod take the thread down? The link doesn't work.

I disagree somewhat in that our gold dome autocrats keep moving the goal posts for those of us with older rigs. This may or may not apply to a 1994 FZJ80, but when my 1987 FJ60 was manufactured in Japan and subsequently tested in Colorado, the standard was ppm, and now it is "grams per mile" on the treadmill. Also, it was simply tested at idle and at 2500 RPM with no load, now they romp on it all the way up to 60 MPH.

Note that the drones who inhabit the testing places are pretty clueless about a lot of things, such as how manual transmissions and clutches work. In trying to get my poor old 2F to make the rollers go fast enough I could hear them redlining it. I once watched a drone pop my hood, look at the right side of the engine bay, close the hood and check off the box for the presence of a smog pump (it's on the other side on a 60, she was looking at the AC compressor.).

To further add to our collective misery, you used to be able to get collector's plates once your rig was 25 years old and be done with smog testing. Now, our esteemed legislators, in their attempt to save humanity from the throngs of old Land Cruiser blackening the sky, say that these same rigs must pass these new, tightened standards every five years even with collector plates, and the ONLY way to routinely skip the dreaded trip to AIR Care for the $25 shakedown is to either pay for some local mechanic's kid's college fund (see above) or have a rig that is 1975 or older. That means my 1976 FJ40 no longer qualifies. Even though it is FORTY EIGHT YEARS OLD and getting older every year.

Ask me how I REALLY feel about smog testing along Califrado's front range...
