CEL for insufficient flow. The whole EGR system is rather new except for the vacuum lines. I've explored a lot with this system and have ran the troubleshooting steps numerous times. Usually I can just suck the valve open and the engine starts to stall and then the truck is good for a few months. This time the valve is opening and the there is no change to engine idle. I can hear the valve open and close so now I'm thinking I could have a clogged area where the flow goes into intake or an exhaust leak?
