I appreciate the replies. This situation is saddening and stressful. My boys and I have put a lot of hours into this van with the interior and upgrades, and now it seems like maybe we made the wrong choice. I really hope I can get this fixed.

I got the other van today. The computer from that van put into this van yields the exact same results. The computer from this van into the new van runs just fine. So computer issues are not the problem.

It does have EGR and it is closed.
