Doug yes you have to remove the EGR valve itself and remove all the carbon inside of it and also remove all the carbon inside the intake this will solve your problem good luck          ragu,          
     do i have to take the intake off of the motor, or just clean out the hole where the egr valve bolts too,the hole is about 5/8 inch . and then you are saying to clean out the egr valve itself once i remove it. i just want to be clear as to what needs to be done.  

Answer
no you don't. But you do have to remove the throttle body if you go easy you can use the old gasket if not make sure you are able to get one . now if you don't to go thru all that then then just clean out the hole and when you scrape it all out just for 2 sec. start it up and this will blow out the small pices that you didn't get out.
