Smog check results (ouch!) 200 1986

Need some solutions here ...

CA Smog II area ... two years ago, passed well below average. This time, failed badly - too high on HC, borderline on CO, and way over on NOx.

Results are as follows:

15mph ... 14.10% CO2, 0.80% O2, 142ppm HC (133ppm max.), .67% CO, 2745ppm NOx (1146 ppm max.)

25mph ... 14.10% CO2, 0.80% O2, 135ppm HC (108ppm max), .63% CO (.62% max.), 2468ppm NOx (1006 ppm max.)

Disconnection of anything is a no-no, as they do do visual checks, but I did read about plugging the vacuum line to the computer, which I'll do. But any other tips? Had the normal tune up stuff already ... guy suggested the O2 sensor could be a culprit, as it does seem to suggest (to me, at least) that it's running on the rich side.

Thanks!

-- Kane ... who afterwards, has to get the '74 smogged.
