Car stalls

Sometimes, especially when cold, my car has a habbit of stallilng. Basically, when moving from reverse to first gear, or when comming to a stop and putting it in netural (it's a manual 5 speed transmission), the revs fall to low and the car stalls. Any ideas?

Also, it's a 1990 Primera with the SR20DE motor

I have the same problem. Its just that the engine is cold. If I rev the engine when I start it, it seems to overcome the problem.;)
