strange miss when engine cold

I have recently started having a miss in the engine when I first start the 79 930 turbo when it is cold (sitting for awhile).
I have changed the distributor cap, wires are in great shape.
When the car is first started it goes thru the normal high idle and eventually drops to around 1200rpm......but it has a distinct miss. Really noticeable when you blip the throttle.
Now if I let the car idle for 10 minutes, the idle speed drops to 950rpm and the miss seems to disappear.
Have not driven the car under load since this started.
What could cause this?
