i have a 99 durango 318 5.2. The issue that i am having is that when it gets really cold outside, my car dies. This only will happen if it gets real cold overnight or it sits out in the cold all day. Yesterday after i got it jumped at work, it would not hold an idle. Ive read a couple things where this could be a bad computer. A lot of people say that its the battery, but this is the second brand new battery i have put on it and it has a new alternator. Any help or suggestions on what to look for would be greatly appreciated!
