Default Failed Emissions test!

The owner that owned my 92 SC before me took an emissions test.
It failed tail pipe emissions inspection.
(I am able to smell exhaust leak.)
This is what it read:

Reading Limit
HC 412 180
CO 0.37 1.20
CO2 12.1
O2 3.73

He had "HC" circled. What does this mean?
Cheers!

HC stands for Hydro Carbons.

Also, if you got no exhaust leaks, but it smells like it, you cat is probably gutted. Time for new one. Situation like that, you would need to confirm the car is in fuel control first. If not, your cat is gonna get deteriorated again.
