Anyone Denver area listers have a CO meter?

[Peter Golledge]

Listers,

The LTQ missed Denver emissions on CO by a hair so I need to do some
troubleshooting.  Does anyone have a CO meter or know of a good source
to obtain one around Denver?  I see lots of peaks/troughs in the CO
readings so I suspect an intermittent fault in one of the sensor
circuits.

Somewhat amusing to do Denver emissions with a Chev powered Audi.
Last year the emissions folk gave me grief with my 930... complained
that their book said 911Turbo NOT 930.

On the LTQ they did not notice lack of engine idiot light or the totally
faked O2 warning light.  Test dude nearly put it right through the
building when trying to get it on the rollers must be  used to those
'other' Audis. :-)

Cheers
