I have a range rover sport supercharged and every time i start it from cold it starts hunting ?

can anybody tell me why my range rover supercharged starts hunting when starting from cold please.|||quite simply you have an air vacuum leak on the inlet side...look for any small bore pipes that have come adrift or check for cracks in the piping.|||The Automatic Gearbox / Transmission needs to be looked at by an Authorised Range Rover Main Dealer / Service Agent as soon as possible to cure this problem !
