Ok, i have a 1997 civic dx, d16y7 5 spd, i turbode my car and put a 93 dx manifold on it so i didnt have the stupid upright manifold the dx has, now i pulled the turbo and driving around n/a but i swapped to a y8 manifold today and it wont idle, it revs up to 2 grand and then revs down real quick and dies. I didnt have this problem with the old 92 dx manifold when i drove around na, but now the y8 is just infuriating my car. any ideas?
