Pulled intake and swapped fuel rails now getting codes.

[Rebel79]

I plugged in the vacuum lines into the EGR. Can't remember if I did anything else to it.

UPDATE:

I drove my Cobra to a friend's house and all of a sudden, the car started to miss, and it had trouble revving. I could hear what sounded like air coming from the motor. The car will not idle at all. I am assuming I blew my intake plenum gasket. Anyway to know for sure? I don't think Ford will be open on Monday so I can get a new gasket.. any suggestions? Oh yeah I used Blue Pernatex to help seal the gasket last time.
