Yes, all reading were within normal range except the NOx @ 25mph, it has
read from 1200 to 1530 . Everything else now passes. What do you think this
means.

 

No, I did not. I drove it over city streets a few miles to the Smog Check
Station. No one ever mentioned I needed to "break in the Cat." Why is that?
Where is this type of information documented?

I repeat the Catalytic converter operates at about 1,600 degrees
Fahrenheit, that's about three times the temperature of a cigarette.
So...... if it doesn't reach that temperature it's not going to
"convert" anything, understand?

Has nothing to do with breakin. The 20 minutes is to insure that the
cat actually is up to temp and in it's working range. Last summer I
had to get an emissions check and had to let it sit outside for a
couple of hours before we could get the bay open. Just for curiosity
- mine and the shop owner - we fired it up and ran the sniffer cold.
Ran it around the neighbor hood for 15-20 minutes, tested again. Took
it out on the freeway and ran it at 70-75 for about 30 miles then
tested a third time. The cold check failed miserably, the light
warmup helped a lot but it was still marginal. After the highway run,
all readings were low to midrange. Convincing enough the make that a
standard recommendation for that shop, especially for older vehicles.
