I just took my 84 CA model in and it failed smog:

2372rpm measured      allowable
35                      180  hc ppm  pass
1.21                   1.20 CO%   fail
2.3                         02
12.9                        CO2

idle 923 rpm meas      allowable
236                    150 ppm hc fail
1.79                   1.20 % CO  fail
9.2                     O2
7.5                     CO2

The previous owner had the original O2 sensor in it at 140k, so maybe this
burnt out the cat. I inspected the cat, and it is _empty_, just the outer
shell remains. Are these emission levels resonable for no cat, but with a
new functioning O2 sensor? I want to be sure before I put a new cat in and
have it burn out. Also, the best price I found for a cat is 99$ from
busdepot.com. Is there anything less out there?

Are the above smog limits correct? I saw someone else with a 90 and the
limit was 240ppm hc, I've also seen 250ppm hc. It would not surprise me if
the shop I went to used the wrong values. Thanks much in advance.
