I believe 0304 is the knock sensor code. I just got an egr code which was 0302. I think the guide tube is where it usually gets clogged up but i'm gonna remove the whole egr system and clean it out.

I saw pictures of someones tube that went from the headers to the egr completely blocked off by carbon. So that may be another place to check.
