    and when im on it then let go it dies.... and first start it sometimes idles high and low then dies. when im at a light with brake on let go of brake then it dies.. I have a bigger cam but not much. 30lb injectors wich i think are to big. Never did this until i changed the plugs and hit some hose wires on my car that idont know how they go back. Looks like smog and stuff. But smog isnt hooked up??
    thanks

    Maybe it is and maybe it isn't... here's a vacuum diagram for the lines on a smog equipped stang...

    Note that on Mass Air equipped cars, there is no MAP, only a BAP. The BAP does not connect to the manifold, but vents to the atmosphere.
