Number one... occasionally when I am driving in cold weather my car seems has trouble idling. When I am stopped at a light my car will rev between ~700 and ~1200 rpms.

Number Two... I think it is probably be related to the first. But when I am driving I will push on the accelerator and nothing will happen it actually feels like if had a choke on if i had one on a car. Also when I am driving and I let off the gas and push the break my car will completely die. It doesn't do anything to warn me that this might happen.

Number three... When my car sits out in the cold one of my rear breaks will lock up from the parking break and wont let loose until. most of the time it will let go really quick and other times it will last almost the whole ride home or wherever I am going. This doesn't happen very often but It happened last night so I thought I would ask.

I apologize if this has been asked before I just didn't really know what to search for. Anyway thanks for the help.
 
1 and 2 could be related. Clean/change the IAC valve and clean the throttle body. Any CEL codes? Take it to Autozone or Advance for a free reading. Then post the exact codes.

3. Need new parking brake cable or don't use the parking brake when it goes below freezing.

Edit. IAC valve
