[DML] Not passing emissions

["M. P. Olans" <mpolans@xxxxxxxxxxx>]

OK,
     This is frustrating.  Two years ago I had to do a full tune-up to
pass emissions.  This year, same thing.  However, even after the
tuneup, my CO is still too high.  NOx and HC's are really low so I
know the O2 sensor and cats are doing their job.  However, I am at a
loss here.  I did plugs, wires, cap, and rotor.  Gapped them to .025
since the manual said .024-.028 IIRC.  Car runs great and has power
just like before.  It is an Island Twin Turbo.  So, any hints?  I'm
running about 25g/mile CO and the limit is 20.  When I got it from Rob
it tested at 11 g/mile, and then after the first tune-up it was also
11 g/mile.  What am I missing?  I cleaned my K&N air filter last
month.  I haven't changed my fuel filter in probably 4 years, but how
could that affect emissions?

What am I missing?

Thanks,
