Car won`t idle until its warm

Hey Pelicans, I`ve recently bought a 1975 911 that is using the stock CIS system on a 1987 3.3 turbo motor. It wont idle until its warmed up. It just stalls. When warm it runs great! The previous owner said he tried to install a new fast idle sensor (I think thats what it`s called...) but it didn`t work, so he wasn`t sure if the new part was faulty or if there was another problem. So he left is as is.

I`d like to try and fix it but not sure what to search out. Should I search for a parts diagram for an 1987 3.3 turbo motor and start trying to trouble shoot from there. Or should I be looking up info on a 1975 CIS system.

I`m a Porsche newbie and don`t know much about electronics but certainly not afraid to dig in a try and work on it. Any suggestions would be greatly appreciated.

Cheers, Chris
