    So, what is the function of the "spout plugs", Nos. 1 & 2 ? The Ford 92 wiring diagram labels No. 1 as a "shorting plug" and No. 2 as a "shorting bar" ? Huh ?

    worked again! got a used 92 SHO, 171k miles. Failed the first time in NJ
    Max NOx = 970 NOx Read = 2741
    pulled the connector
    Max NOx - 970 NOx Read = 959 (15 degrees cooler in the morning as well)

    Thanks for this valuable information for the people in Ontario Canada. I have looked for this connector in the past, after hearing about how effective it is..... but could never find it.

    A request of those that reply to this thread - can you indicate all three emissions levels (before and after), as well as which shorting plug that you pull?

    I removed the OCTANE ADJ/shorting bar as currently I have HC at 66 (100 limit), .3 CO (on a .5 limit) and 1700 NOx on a 1100 limit. The engine ran a little rough but smoothed out after a few minutes. However, the Check Engine light is on - (turns out it wasthe MAF plug duh) will having a check engine light showing on a 95 MTX cause it to fail automatically (in CT) - no, it will not effect an OBD-I cEEC-IV car in CT?

    As far as I know, they only go by a sniff test on EEC-IV vehicles here in CT. I know they won't pull codes if the CEL is off. But if the CEL is lit up like a christmas tree then that might lead to something different.

    Have you tried clearing the codes and CEL by disconnecting the battery for 5-10 minutes? If so, how soon after being cleared does the CEL come back on? What I'm suggesting is that maybe you could get it to stay off long enough to have the test performed.

    As noted above, pulling the OCT ADJ plug retards spark timing by only a few degrees, and that small decrease applies straight across the board. So it may not be enough to decrease NOx to a level that's under the limits, especially at higher revs when the timing is being dynamically increased by the PCM at a greater rate.

    To clarify, will the Check Engine Light come on with the SPOUT pulled?

    My check engine light turned out to be the MAF, which I had disconnected to improve access to the "3 degree retard" shorting plug. This 3 degree plug did not have much effect on NOx levels, but then again the MAF was unplugged so take this FWIW.

    I had to run a couple of tanks of premium and then pull the shorting bar behind the intake near the passenger side of the firewall.

    +1 on the SPOUT working. Previous emissions test showed 23XX NOX. Pulled the SPOUT, car ran like an SE, not an SHO lol. NOX dramatically reduced to 312 PPM, allowance was 1167 PPM.

    I have a strong feeling that a car with no cats, with faux heat shields welded on (visual inspection), a pulled SPOUT, and 'clean' tune would pass emissions no problem.

    So if this happens how do you fix the problem?

    Have codes;
    121- TPS out of range
    219- Spout circuit failure timing defaulted 10* Ignition Spout or Saw circuit open or shorted

    First check for the missing "plug" that completes the SPOUT circuit, as seen in the pics in the original post.

    Also, you can perform some diagnostic tests on the SPOUT circuit. You will find those tests outlined in this article (scroll down to "N20"):

    DIS Troubleshooting - No Start Pinpoint Tests

    (The SHO and SC DIS systems are the same).

    Well this weekend Jeremiah helped me with swapping out the DIS and the PCM from a properly running SHO also checked the SPOUT Connections and all are plugged in but still no change. The car still has a defaulted timing at WOT any more suggestions?

    not sure this is the proper thread for this. Just because you get a 219 doesn't mean its a problem with a spout connector. I would try checking your TPS voltages first. That is the more curious one, 219 is just what is thrown when the computer can't make sense of some signals its getting. Safe mode.

    Testament to pulling the SPOUT! Works wonders.....

    Test 1:
    HC: 100.0 LIMIT: 114.0 PASS
    CO: 0.68 LIMIT: 0.63 PHAIL
    NOx: 1666.9 LIMIT: 796.0 PHAIL

    Test 2:
    HC: 9.4 PASS
    CO: 0.02 PASS
    NOx: 391.7 PASS


    Good luck everyone!

    Another testament that pulling the spout works.

    Before:
    15MPH 25MPH
    HC 163 184
    CO .28 .34
    CO2 14.6 14.5
    O2 .4 .5
    Nox 1343 1562


    After:
    15MPH 25MPH
    HC 68 103
    CO .12 .25
    CO2 14.7 14.5
    O2 .3 .4
    Nox 416 508

    hopefully we'll be able to replicate these results with Bob's 92 down here in AZ tomorrow.

    but which should we pull? the one on the passenger side fire wall? or the one by the coil?

    my 91 passed without cats back in 2009.

    Pull the one on the passenger side firewall. That is the one I pulled.

    This tip has saved the day again...

    I have an 89 w/ SHOSource equal length Y pipe & the high flow cats that came w/ it. Also new O2 sensors installed at same time about 12,000 miles ago. I also had completed the 60k service w/ new OEM plugs & wires. It passed easily last year shortly after all was installed.

    This time however it failed only the low speed emission (15mph) while (barely) passing the high speed (25mph) emissions:

    Low Speed;
    HC - Standard = 167 / Reading = 206
    NOX - Standard = 1273 / Reading = 2996

    After cleaning the MAF sensor & putting in a paper filter & pulling the spout plug:
    Low Speed;
    HC - Standard = 167 / Reading = 43
    NOX - Standard = 1273 / Reading = 368

    Yahoo! much to wife's distress, the SHO gets to live in the driveway another year!
