CHEVROLET CAVALIER TUNE UP PROBLEM

2001 Chevrolet Cavalier • 115,000 miles

I had a problem with my catalytic converter for and have replaced it twice after the check engine light turned on. My mechanic said that I need a tune up and that is what is messing with the converter. What does a tune up entail and how much does that usually run? I purchased the car a year ago and have not done a tune up. How often should I be doing that?

Using GM CAT? Code P0420?
