Long Warm Up and RPM Surge

Hello everyone new to this forum but not new to Porsches I have had 5 Porsches over the years 1981 911 1985 911 1985 928 and currently 2004 Cayenne and 1980 911 Convertible built from a Targa I can't believe this forum this is one of the best I have ever seen. Hopefully someone can help me with this I just purchased the 1980 911 it has 94,000 miles on it here is the issue. When it is cold and I start it the engine sputters and begins to stall this continues for at least 10 minutes or more. When I press the throttle to keep it running the RPM's shoot up to about 3000 and stay there for a few seconds even when I remove my foot from the trottle. Once it warms up it idles better but I still have the problem of the engine reving even when I take my foot off the pedal. When the car is idiling normally it idles at about 800 but as I said if I take my foot off the gas like when coming to a stop and press the clutch the idle is around 3000 for a few seconds. Any help would be greatly appreciated thanks Mike
