Hi,

My mechanic thinks my van wont pass smog because the
cat isnt getting hot enough(meow, purr), therefore I
need a new cat.

These numbers dont mean much to me:

IDLE 0.17% CO 135PPM HC
2500 0.35      90PPM
Before CAT at IDLE 3.65% CO 290PPM HC.

I have already order the new cat and will replace it
tomorrow, but was wondering what you smog pros thought
about this diagnosis.  I guess they used some kind of
infared something or other to tell if the cat was
getting hot enough...

Thanks,

Jeff
