Failed Emissions - HC only - 87 900t (longish)

Reading was 4 - allowed in Mass is 2 (not sure of units). NOx and CO are fine. I have searched other posts and the FAQ and it looks as though my Automatic Idle Control valve may need adjustment, but this procedure involves use of a computer which I don't have. Car runs and idles fine. I would love to tweak a screw somewhere and get it within spec, but may have to go to Charles River Saab if a computer is involved.
Any suggestions?
It passed last year and I have adjusted the timing from 12 degrees BTDC to the correct 16-17. Maybe that is what messed it up but it definetly ran better (more responsive) after I did that.
