That would be the reason it goes nuts when I start it up, It barely runs, jumping around in the rpms til the car warms up - then its okay. The guy who did the swap said its because ive got an open air bov, but the bov was brand new and its closed during no boost.....so i dont see that causing anything....any other places i could have a vacuum leak? - blake....if you can fix my car ill throw ya fifty, what ya say?
