Now I feel stupid..called the dealer, after another Kragen told me it is a dealer part...and they said it doesn't have an EGR valve.
The issue: Sometimes at take-off, the van will hesitate a bit. Be jumpy, not like it's going to die, but almost like it's not getting enough fuel, just for a second or 2. It doesn't happen every day, sometimes not for a couple weeks. This has been happening for the last 15 months. The only code I get is 400.1. What is this, since I can't find this specific one.
