Sounds like an egr valve symtom. Carbon deposits lodging valve open. But cant be related to removing the intake. Are you sure that you have all the vacuum lines on correctly? Check the vac lines and take off the egr valve and see if you can blow through it.

is it a wire or a hose that is "broken" def fix the obviously before you try to do anything else, find a pic of a 2.2 engine and use paint to show us what is broken
