Code 420

I have a 1997 D-90. The check engine light periodically comes on. Occasionally it will go out on its own. I purchased a code reader and it displays code 420. If i clear it out the light will go off. It usually comes back within a week or so. Any ideas what may be tripping this code?

Thanks

Mark

There I feel better

Code 420 is a cat / O2 sensor issue, right?

Thanks for the input, i had a feeling the sensors may be the issue. "Mexican Americans, don't like to get up early in the morning so they do it really slow...."
