The engine surges for the first couple of miles driven until the engine warms up on 2009 Chrysler Town & Country

Recently the engine has stopped running a couple of times at slow speeds when I take my foot off the accelerator. When that happens I get a p0406 engine code an a check engine light. What is the most likely cause and fix for these issues?

That is an egr valve positon sensor circuit falt, the earlier year models had some problems with this which Chry was taking care of, call dealer and inquire.
I will call Chrysler,
Thank you,
