[James]

By the sounds of it you have a massive vacuum leak, the sucking sounds give it away

[veg_10]

hey its not the cold start because it just happend 1 day wen i started it hot i thought it was a vacum leak im geting a mechanic to chek it out in the next few days

Sounds very much like a manifold vacuum leak.

Over revs on idle or rev hunting is almost always a vacuum hose come off or a broken line. Look for the little black lines around the throttle body, and if you use your ears you can find where that sucking noise is coming from. Pretty well bound to be the answer.
