Thanks for the help. I will pull it off one more time and check/clean. I don't think this is the problem. I still think it is in the relay to the egr valve.
I will have to trace it to see where it comes from and then check to see what turns it on and off.

When you talk about the plunger and checking under it are you talking about the small hole with the screw? If so how do you check under it?
