Re: [DML] Not passing emissions



Matt,

Would leaning the mixture for the test be worth trying?  Just a thought until you can find the real problem.

  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,
  Matt
