Remove the idle valve located beside the throttle body. Clean it out with some injector cleaner and fit back. This will keep you out of trouble for about 6 to 8 months.

Sounds like your Idle valve might be on the blink, mine had same trouble.
Takes around 10mins to remove and fit a new one (around £50 on ebay) (around £150 from dealers). You choose.
If you need fitting instructions, just reply and ill sort you out. :o)
