Having problems with your 1999 Chevrolet Corvette ?

I continuously have my check engine light come on and the code is always the same PO442. I checked the code numerous times to make sure there wasn't a new one and it's always the same. I know this is a "small emission leak" but it really is a pain in the neck. Are the 1999 corvettes noted for this problem? If so where is the "small leak"usually at?

So I have a couple codes reading po128, and I know thats a coolant deal (hopefully, I haven't checked yet), and the other, is code po442, evap emission, small leak. I have a 2001 Chevy S-10 and need to smog it in the next couple of weeks. Will these issues prevent me from passing smog? I understand they need to get repaired, but my biggest concern right now is the smog check.
