ok, i've been having serious problems with my zc swap. the zc was a dpfi motor, so we took that intake off and put on a mpfi intake, and everything bolted up just fine. my question is what to do with the egr vacuum line, cause when i plug it up, it runs like ****. did i miss something, or what?? as far as i knew, this was supposed to be an easy swap, but its turning into a vacuum night mare. so my cars been in the garage for two weeks now cause no one has any ideas whats wrong, and i've search about 2 dozen different items. plz help, cause i can't figure it out.
