My idle started jumping from 500 to like 1200 when Its stoped it jumps up n down I think its something with the mass air not sure? Then when I accelerate u hear a deeper sound like if its escaping air kind of like a helacopter but lower what might it be

Could also be a vacuum leak or idle air control valve.
