I've got an 01 silverado z71 5.3 and the other day I was drivin and I looked in my rear view mirror and some lady was ridin my tailend so for the first time in forever I stomped on it and when i did, from the engine it sounded like my intake was suckin up a bunch of bugs. thats the only way i can describe it. It makes it seem like im suckin stuff up from the intake..i don't know what it could be but im not to sure..Anyone have the same problem? my moms tahoe 5.3 and my friends silverado 4.8 and 5.3 does the same thing but then others don't
