loud sucking or blowing type noise
ive got a 2000 4.0 rig with about 88k on her and every now and again it makes a loud noise sounds like a sucking or kinda a blowing noise. at first i thought it was my train horns with a slow leak but its nots constant it comes and goes and when the truck is running. it makes the noise under idol and load. i think it might be a vacuum problem but i dont notice anything under the hood.. and like i said it comes and goes so its hard to isolate were exactly it is coming from. i did notice it does it more in the colder weather as its starting to warm up i am noticing it is happening less frequently. i have also noticed if it starts making the noise and i briefly hit the gas pedal hard it will stop. anyone know of what could be wrong or has had this happening on there rig. thanks guys for your help
