i'd double check to find out about that missing vaccum switch you talk about.

i'm not familiar w/ ca smog testing but here in tn i had to cheat a little. i lowered the idle rpm a little and retarded the timing quite a bit to. if you know someone who has a consult then they can really help you out by tuning the car to run lean/clean.
