Fixkick,
So what sensor actually throws the 51 code? Is it the sensor on the EGR main valve? Or is the vacuum side that tells the EGR Main to fire? How does the sensor determine there is a problem to fire the CEL?
I think my issue is the clogged port. It looked totally restricted. I took off the sidewinder pipe when cleaning since I didn't want the carbon to drop back down into the pipe. That pipe is a bit of a trick to get out. It feels like you may break a post when pulling it out and putting it back in.
