GM MAF install, now EGR flow CEL

[justin0469]

So I just got my GM MAF setup together and running. After awhile, I got P0400, EGR Flow. When I searched, I found some people say to just replace the EGR valve, some say that doesnt work. Some say block it off, I don't know if mine is or not. Some say that the vacuum line came off their solenoid. Any other ideas possibly related to more airflow after installing the GM MAF? Where is the EGR stuff?

When I installed my blowthru setup I accidentally pulled two lines off the EGR. I didn't notice it until I was about to the start the car and then I fixed it, so I can't say if that would throw a CEL or not.
