hello all, I posted not the other day about an egr valve problem. We are getting code 34 Egr valve stuck open. First does anyone know it this is something that can be fixed by cleaning the valve or not? Now the bigger problem. Now the truck starts but shuts off as soon as the starter kicks out. The truck will not even idle. Is this just a sign that the egr has completely stopped working? Any info would be greatly appreciated...

Thanks
Nick
