One thing that's been recommended to me before is to have fresh oil and oil
filter. Also, make sure the engune is good and warmed up when they test it.
Make sure your timing is correct as specified on the sticker (they check
that paranmeter). Looser valve lash is better and you want to make sure
you're not too rich (don't forget to make sure the choke is all the way
off). That's a good way to fail if you overlook it. Make sure you have new
air cleaners or ones that are in good shape (there's an air cleaner on the
air pump too.. Electronic ignition may help. Make sure that all your
emission stuff is hooked up and working properly. It's not unusual for the
air injectors to be carboned up and plugged, so you might want to check
your air rail and head ports for blockage. Check belts for slippage. In
California, they check the car at idle (between designated RPM) and at
medium revs (about 2500 RPM), so I don't think a high idle will help you.
Again, in California, If you're unsure, a pre-test can be done before you
make it official. Here, once you're hooked uo to the computer, the results
go directly to HQ in Sacramento and you don't get a second chance. Then you
have to take the car to a special referee station and yes, things get
expensive.
Good luck!
