Exclamation 400E Rough Idle when cold? WHY???

Ok techies....

92 400E :

Within a couple of months ago, I replaced the plug wires, plugs, fuel filter, oil and oil filter, engine wiring harness and air filters. When the car is cold, and I first start it, the idle bounces up and down and the car runs sorta rough. This problem is even WORSE if the car has not been driven in a week or so. When it's doing this, if you give it pedal, the car dies when the RPM's come back down. This lasts about 5-10 minutes until the car gets warm. What could be causing this???
