Thanks for the helpfull replies guys, I have cleaned the system and replaced the valve, there are many helpful post on the forums about how to do this, it works fine, and have replaced as needed, but some on the forum have deleted or blocked off the egr, and I have run egr deletes on other vehicles. However, there were concerns about raising cylindar temps if deleted on the vx, or oil burn off increasing. There were also reports of possible mpg increase and decrease, engine noise decrease, etc. I was hoping some of the users who had done this would update if they experinced this or if they still recommended. I just hated to revive several year old dead threads.
