Why is there a delete plate where the EGR valve goes on my 06 Element EX 2.4L?

I was just wondering what to clean or replace before I put my new Cat on. Thanks

I'm not imagining a necessary cleaning of anything before installing a new catalytic converter. Your converter, if failed, likely failed due to excessive consumption of fuel due to an air intake leak of some sort, or an engine misfire. Hard to know the whole story from your question, but all that to say: I don't know of anything that needs "cleaned" before installing a catalytic converter.

Thanks Dave. I did replace the PCV valve. It was clogged up. The Element has 140 thousand miles on it. I should have changed it a long time ago.
