well this weekend i ported my upper intake manifold, and now when the car is cold it wants to die? any ideas as to what this is or how to fix? just so you know i have done the tb mod so i know it's not the cold start or cam i have still to try adjusting the bac but that's about all i can tell. also the 2 vac hoses on the intake manifold that go to the steel hoses behind that manifold does the farthest one go on to the top steel hose or the bottom.
