99 e250 trouble codes
just bought a 99 e250 ext cargo van.
ran the obd2 and got these codes, can some one tell me what they are and how to fix?
thanks

I actually think it might be just what the code says, a plugged downstream line. There is an orifice in the Manifold to EGR Intake Tube Assy that allows a certain amount of exhaust gas to be vaccumed into the EGR assy. If that corrodes or gets plugged, you will throw a code since the differential pressure becomes too high on exhaust side. The nut / bolt at the exhaust manifold is pretty corroded. Looks like it will fall apart if I put a wrench on it. Can't find an online price for that tube (item 10 in some engine exploded views) so I just asked a parts person (my son) today for the pricing. I need the van to pull a trailer so I don't want to touch it unless I have a replacement available.
