Home for the holidays now and my car is parked outside, the first time it's been parked outside in below freezing temps in probably 3-4 years, otherwise it is garage parked and typically when I come home I steal one of the garage stalls. Well, this morning I had to move the car for my Mom and it would not stay running. It would start and then die once the rpms settled back down. I would have to pump the gas to keep the car running and then once it was at operating temp, it idled and drove completely normal.

Weird symptoms:

-When tapping gas pedal to keep the car running, doesn't feel like it's responding the same as it does when warm, pumping the gas pedal wasn't instantly reving the engine, sometimes it would, sometimes it felt like it wouldn't or be extremely laggy
-I felt like the car got up to operating temps way faster than it normally does. The car sat outside last night, it was cold, in maybe the three minutes I had started it and slowly pumped the gas pedal to keep it running, it was at operating temp. It might be my imagination, but it felt like it was way faster than it normally would take.
-It has never ever done this before until today. I went back outside a few hours later because I had to move it again, and it was the same thing, would not stay running until it got back to operating temp and then it was completely fine.

Factors:
-I am venting completely to atmosphere, I am not running a PTC of any kind. I've heard that that can be a problem with freezing? Is condensation freezing in the turbo not allowing it to spin right away and thus not letting air into the engine?
-I think my battery is on the way out, after the car sat for 2 weeks without running the battery was completely dead, it also lost .5 Volts over night two nights ago, however, the car started right up each time it died this morning, so I do not believe this is battery related.


Specs:

1994 850 Turbo
FMIC

Venting to atmosphere-NO PTC


I have the car in the garage right now out of the cold. I will start it in a few hours to see if it starts normally. If it does, I know it's temperature related.

What would cause a car to not want to stay running in cold temp start ups?

Thanks for all of your help.
