sounds a LOT like the vacuum leak that I just fixed on my 911. Actually it was more like lots of little leaks that added up to one huge leak. The biggest leaker was the vacuum line between the heated air vent from the oil tank to the throttle body. The vacuum line at the thermo valve at the back of the throttle body was split at the end, which caused at varying leak, depending on ambient air temperature. When the weather got colder, the leak got worse. Mine ran ok at high rpm too. It was low rpm that was the pits.
