failed emissions, low co, high nox

posted by  someone claiming to be kswan on  Fri Sep 16 15:52 CST 2005 [RELATED]

I failed the emissions test here in Ca. on my 87 240.
The readings on the CO were very low (.01) and high on the NO (1028 @ 1139 at 15mph and 25 mph respectively).
The HC reading was fine (30) and the car runs and idles perfectly. My NO readings are always on the edge with my bricks but this one's a bit our there and with the CO being so low I'm a bit puzzled.

Any help would be greatly appreciated.

K.S.
