So im a new 964 owner, i started driving it at the beggining of the summer and loving it, but the only thing thats driving me nuts is the stalling issue when its cold, and also when its warm it will stall if i dont rev it up when engaging the clutch on a bit of a hill, ive replaced the idle stab valve because of random stalling which is fixed, i also checked temp sensor, and i also did a smoke test on the intake,found a few small leaks but nothing really major, i also checked the fuel mixture which is perfect, the engine runs great other then the stalling.

Could be the throttle stop micro switch.

i had a similar problem that was fixed by ...

a) system adaptation by bosch hammer

b) resisting the temptation to add throttle during start-up

c) turning the key to position 2 and waiting for a few seconds before moving to position 3 to start

I also found the clutch super sensitive compared to my previous manual cars, so it needs to be treated with micro finesse when taking off.

I experienced the same symtoms right after I bought my first 964 C4. It turned out to be a firing sequence problem. The previous owner crossed 4 & 5 lower plug wires.

I also find the clutch to be more sensitive and treat it with a bit more finesse on take off.
