Can this hose thing cause a vacuum leak?

ok i own a saturn sl1, like the one in the video im goin to show you, now i was messing with it today cuz it has been running wierd and everybody said it sounds like a bad vacuum leak,



things that doin wierd stuff on my car



when start, goes up to 3000 rpm and does down slow,

when in drive or %26quot;r%26quot; while your foot is on the brake it shacks, idles lowish, and sometimes just acts wierd, also check engine light is on and flash's alot,



i replaced the oxygen senor, the fuel pump and filter, spark plugs with spark plug wires, i am changing out the coil friday,



now here is my question, i think!!



ok on this video http://www.youtube.com/watch?v=mYa8rcHeN3A is a guy wth a saturn like myne, ok see from 0:15 to 0:20 on the video how he puts his hand on that black thing and follows it up, now were that black hose it hooked on the throttle body, and the end of the black hose, on 0:20 that end was melted and i thin that is a vacuum leak right? the black end peace is melted and there is a opening, so im guessing that a vacuum leak? thank you guysCan this hose thing cause a vacuum leak?
Hi



What you have is an intake air leak, and it is bypassing the airflow meter and causing the problems you are having.

yes we know all that stuff and another thing that,s a good way to catch the engine on fire if the engine is hot too. any hose that,s drawing vacuum there could be a vacuum leak if the hose or metal tube has a leak in it.
