over the past couple of days i have noticed an unusually loud hissing sound coming from the passenger side. when i popped the hood i thought it was the intake, but after putting my stock one back in i could still hear it. it is coming for somewhere in the vicinity of the intake but i have given up and i have no idea what it is. i have a 96 gt, does anyone know what this sound is?

id assume a vaccuum line somewhere disconnected or broke if it isnt ur intake or maybe throttle body gasket??

Check your PCV valve out.
