Read up on the CIS/E system:

Check out 07.3 and be aware that there is a potentiometer attached to the CIS throttle plate which goes bad. They are available and can be replaced but need to be properly calibrated.

You must also keep the car HOT as much as possible. Keep the car running while waiting for the test.

My last emission test also had high HC so I'm probably going to have problems next year, emissions are tested every two years in Virginia.
