In addition to what the others have stated, especially testing the Cat, ABV, and timing, it helps to run the tank down low in fuel. That might keep the evap system from dumping the extra fuel vapor into the system. Add the Heet with the tank low. You can also go higher on your idle.

My guess is a weak air pump or bad Cat.

Good luck and post up with what you do and what changes in your readings.

For a couple of years, I had to put a pint of rubbing alcohol in a low tank, let her warm nice, and run the test. Ran hot, and good enough to pass the test, and filled the tank with gas right after the test. My vacuum lines weren't routed correctly, and added to poor emissions. Once I got them corrected. I have had no problems passing since.
