Could be your CCV system is involved. Have you done any maintenance there?
If you get the car to a warm garage does the situation change? Cold weather always seems to bring up issues that weren't issues when it was warmer.
I'd also check fuel pressure and vacuum leaks. Lots of o-rings and gaskets shrink or get more brittle when it's cold.
