Ugh I'm losing my mind here! So after redoing injectors, I had gotten it running. It would cut out at the end of first if I'm stepping on it or early into second if cruising, doesn't stall just no response. I went to take it apart again, my intake manifold bolts were loose. So I just redid cooling system, valve covers and lower and upper intake manifold, used shellac on everything and a torque wrench, just went for a drive same exact issue. I do notice air sounding like it's leaking/hissing near the throttle body on driver side of the intake, by the injectors. Spraying starting fluid near there had absolutely no effect on it. In park it will rev all day long no problems. Only in gear will it cut off I'm moving any faster than a jog. Can anyone help me I'm lost as to what it could be now.
