Default 93 civic failed

I have a 93 civic si with 227000 miles I repalced the cat a year ago and I failed smog, just barely, in northern california.

Hydrocarbons (HC)
MAX. AVE. MEAS.
15MPH. . . . 93. 21 . 93

25mph. . . . 59 . 13 . 60

Everything else was fine.
I read some of the suggestions below and I was wondering if they would work in my case as well?
