Gross Polluter-->Passed

[Theron Ross <ross@sanoh.com.mx>]

Just an update on my '81 Gross Polluter S:

I installed a new O2 sensor and cat and it passed--oh yeah, I also changed
out the K&N (didn't have time to wash it out) and put in a slightly used air
filter.

Here are the measurements. The top part is when I failed, the bottom is my
passing score:

	%O2			HC (PPM)			CO (%)
NO (PPM)
	MEAS		MAX	AVE	MEAS		MAX	AVE	MEAS
MAX	AVE	MEAS
15mph	0.5		162	352	177		1.09	2.59	0.74
1318	2382	3148
25mph	0.3		132	282	122		0.89	2.39	0.55
1178	2182	1800

15mph	0.1		162	52	13		1.09	0.20	0.01
1318	475	719
25mph	0.0		132	32	1		0.89	0.14	0.00
1178	499	29	


The old cat looks fine, so I don't know if it's actually bad. The "innards"
seem to all be in tact, and I can see light through most all of it. I can
see some of plugging, but not a lot--maybe 5%.

I am planning to have my CIS professionally tuned though, as Eric and others
suggested. Anyone have a recommendation for someone that can do it for me in
SoCal? You know of anyone Shawn? Larry?

Thanks to everyone for all the help.
