:tdown: I went to go get a smog check today and I failed. I passed everything but on the idle HC (RPM). The Max is 100, GP 250, and MEAS 290. This is the second time I got denied. But in the 2 year interval, I sacrificed a crooked tech for some $$ and this year I tried adding a RPM fuel regulator. I read the threads assuming that I should regulate the pressure to 35psi, put regular 87 octane (1/2 tank full, half 87 and 91), run the engine hot which I did about 50mi then adjusted the pressure 12mi before going to the test. I don't what else to do?

Pretty much the same story with mine. http://www.syty.net/forums/showthread.php?t=61111
I think that when the Tech just lets the throttlebody snap shut is what kills us.
Anyways, I'm freshening up my motor so hopefully next time it will be a cinch.
Wow, and it looks like they lowered the F'ing spec. for idle HC. It was 120 when I went last year.
Bastages!!! :rant:
Get a 3 bed catalytic converter. It costs more but will run cleaner.

I passed the emission with out a cat in PA. The tech showed me a trick. Keep the RPM's up at the end of the test (the last 30 seconds). This will give you a different reading. Also, cheap gas? I would run High OCTANE and if you have an ultimate, go to Valet!

Lower octane combusts at a lower temp therefore you get a more complete burn thus cleaner emissions..

Denatured alky in the fuel tank works also.

Yep, that works also,but the tech should not see that you have a CEL on.

Somebody had made one or two for a coulpe guys I had heard before.

With the 3 bar you'll lose a little resolution which shows up most at idle.
The bigger cam will cause a little bit more of a problem.
You need to lower your VE in the idle area and lower your o2 settings.
Get a good log and see if Nolan will lower your o2 settings & pull some fuel if needed.
If the snap close of the throttle is a problem, there's a constant in some bins for that. It just adds a shot of fuel when coming out of DFCO to wet the walls etc.. Since it is a constant it adds the same pw. So if you double the injector size you double the amount of fuel in that pulse.
Not all bins have been hacked far enough to find that particular setting. I don't recall if $58 has.
Little crap like this is why people need to learn the basics of doing their own chip......
As a last resort I can change your o2 settings for you. I'll need to dig my PC and autoprom out of storage to do it since I just moved back to cali. That's assuming Nolan doesn't protect his bins.

Around here, I am pretty sure they don't worry about cel on pre 96 models. Only the sniffer.
