I couldn't get it to do anything backprobing the pink wire and hooking it to positive battery post. I took it loose from the car and when I turn the ignition on and off the plunger goes in and out on the egr.

Do you have a p0401 code also? Try unplugging the egr valve and running the car?

I haven't cleaned the egr valve itself But with the plunger moving in and out when I turn the ignition off and on don't that indicates the egr is working or could it be stopped up internally itself?

I don't have a p0401 with the egr unplugged. What's up with that?

Ok I would do more tests on a better diag tool but looks like you are having a intermittent issue with the egr. What brand position sensor did you put in.
