type44T cold start problems..

Sounds like a vacuum leak. Take off the oil cap while the car is running. If it dies, you probably have no leaks, but if it continues running (even if it's rough), the mixture is likely over-compensated for the leak. Other important things are the idle temp sensor and wiring. I would make sure all the wiring has close to zero ohms going from the sensors & switches to the idle control and ECU. Could even be the idle control unit. Do a tune-up if needed. Check plugs, wires, cap, and rotor. The fuel system may have issues... If you close the full throttle switch, it will give it more fuel. Does that help? Does playing with the mixture screw help? If so, check for proper system and cold/warm control pressure.
 
Good luck.
