cold???

i have a 91 civic and everytime i go to start it in the morning it wont stay on... now i live in ct and its cold at night now..so i was thinking this could be part of the problem..it turns on fine but wont stay on unless i hold the gas pedal down for a little bit and it warms up. but it gets kind of annoying having the rev my engine up every morning to keep it going. Any Help!!!!

Could be a bad ignitor, or either of your two idle sensors: FITV or IACV.
