    If I read this thread correctly...

    all those who passed emissions after a spout removal did it with the firewall located spout connector removed.

    has anyone tried to see if just removing the octane plug spout (near coil pack) will make enough of a difference to run cleaner? The reason for my question is i think I'd like to run 87 octane in the car and I am going to let my 18 yr old son drive it so a little power loss with a trade off of cheaper fuel costs and emissions test passing might be the plan...

    Many of us have been running 87 octane "as is" for 20 years now. No problem on a stock car. Just try the spout first if you have an emissions issue.

    See this article from back in 1989:

    Re-tested AZ emissions today. Failed on NOX first time through.

    Cleaned MAF, new air cleaner, replace cracked rubber boot for EGR vacuum line, and... Pull firewall SPOUT right before pulling into test center.

    Before:

    Test: Result / Standard
    HC: 0.51 / 0.80
    CO: 7.25 / 12.00
    NOX: 2.52 / 2.00 (Fail) :madflame:

    After:
    HC: 0.59 / 0.80
    CO: 6.02 / 12.00
    NOX: 1.43 / 2.00 (Pass!) :woo-hoo:

    Looked at this thread to see what this was all about...

    First off, THANK GAWD MI doesn't have EM testing. Also, if they do anytime soon or if I move I'll know how to get around that BS!

    Thanks! :)

    I would do it with the car off. It should work either way.

    Just ran through emissions in Tucson. Kinda nervous, as this was the first go-through for this car ever. She lived in a non-emissions area of New Mexico with the first owner until 2000 when I moved her to Sierra Vista, AZ, which also didn't have emissions.

    Well, Tucson does. So, two months after her 27th birthday, onto the rollers she goes.

    I preemptively pulled the the spout, but looks like it wouldn't have been an issue as Tucson apparently doesn't pull NOx numbers.

    So, 230K+ miles, somewhere around 100K on the 3.2 I dropped in two years ago, 10+ year old magnaflow cats:

    HC idle (PPM): 43/220
    HC loaded (PPM): 33/220
    CO idle (%): .06/1.20
    CO loaded (%): .43/1.20

    Emission tester guy was kinda shocked at her low numbers :)

    There reaction is the best when you come back with literally half the emission level. Another sho goes on.

    I gave this a try today on my 95 ATX, which has always been right on the boarder of failing, and it cut my numbers by half, a substantial drop. I got a spare jumper and removed the pins inside, and swapped the jumper plug, so that if the smog guy was to know what the plug was for, it would look correct. Definitely made the car feel like a slug. Will have to do this on my 90 when it is due, as it literally is one point from failing.
