Codes say it may need replacing. If anyone has a thread for procedure, I would greatly appreciate it as I can probably do it myself. Also where is the best place to pick up a replacement for a decent price?

EGR valves hardly fail..Don't bother replacing, u wasting your $$. Do you have EGR hi/lo flow code?..if so, I was running this code for a month..my problem didn't go away until I replaced EGR solenoid valve.

right. i need to replace the solenoid valve. its killing my gas mileage because of gunk. was it easy to do? thanks for the speedy response!

I didn't do it myself, took it to a mechanic..however, thanks to Dave SZ, this will help:
