Re: california smog

Try to find a friendly smog guy (mine has a gorgeous GN) and get him to run the SY with the machine on "manual." That way he can tell you how far off you are and it doesn't get sent to Sacramento. He can't tell you -for sure- that you'll pass but he can come close.

Re: california smog

There are different types of cats.
Need to make sure the cell count is high, the cheaper cats have a low cell count & does not burn most of the fuel.

Why was the test @ 15 & @ 25 MPH?

That is a good point. These trucks are AWD so the test should be a idle and 2500rpm test only. Did you go to a AWD Smog testing place ?

Re: california smog

If you disconnect the tan wire w/black stripe you will get a C.E.L. (check engine light), meaning, if the tech sees it, he will fail you.
