Check to make sure you didn't accidentally disconnect the intake cam sensor. It is easy to do and easy not to notice. You will have to remove the air box.

Did you plug the small vacuum line from the fuel pressure regulator back into the CVV?
Did you replace the O-rings on the air spreader?
You still have a vacuum leak. May need a smoke test to find it.

You need to do a smoke test, there is probably a vacuum leak.
Can your code reader display freeze frame? If yes post it.
