If it’s never had the catalytic converter replaced, you can start there. I used to have a Chevy Blazer of that same year, it failed emissions in several categories. New cat installed, every reading dropped quite a bit and it passed. Once enough time has passed, they don’t work as well as they used to.

This is just a general suggestion, however. If you tell us what it actually failed on (NOx, CO, hydrocarbons), we’ll tailor suggestions to meet that problem.
