It usually is a carbon build up. take off egr valve, use a scraper or wire wheel to clean it, same with manifold, don't use chemicals on the valve itself, but I guess you could use brake cleaner on the port of the engine if you can't scrape it out. get a dremel tool with the long flex extension, put on a wire wheel and clean it out like that
