Probably your IACV. Try cleaning it.

hmm, possibly a vacuum leak? I had the same problem and it was the IACV so I dont have any other ideas, hopepully someone else can chime in.

it goes away in 5 minutes , it only happens when the car is cold, once temps reach a bit its good, so its not vacum right ?

I had a bouncy idle and what fixed it was replacing the throttle body gasket.
