Well i swapped my 88 manifold back onto my car after having my 89 manifold on i had everything hooked up so i start car and it jumps straight to 3k and revs 3 times that high then it dies when it revs it makes a whine scream high pitched noise....I did change one thing i tightened my throttle cable it was pretty loose First thought is vaccum leak and i have a new lower intake gasket from mazda coming ?????? what is my problem -Gabe Medo
