Default Re: Jerky Saturn problem narrowed down to EGR valve. What next?

I'm really glad this thread popped up. I have an EGR insufficient flow code that comes and goes. I've tried all the usual cleaning fixes/replacements but never thought it might be a clogged cat. Definitely something to check - thanks!
