<font size="+1">I'm trying to get my Van licenced here in Oregon where
they have a dyno smog test.<br>
It looks like for the test they make three runs from a standing stop to
about 30mph.<br>
<br>
The problem is that although it is passing the THC, and CO measures, it
is failing the NOx test.<br>
(Standard is 4.62 - my vans is measuring at 11.59 - almost 3x the
standard)<br>
<br>
Any suggestions on what to look for?<br>
The van has been fairly recently tuned up and is in good shape, I do
have one cylinder with compression below all the rest.<br>
<br>
