Problem: The engine will stall on cold starts. If I shift into reverse or drive. The condition is made worse when I come to stop on an incline. The cold fall/winter temperatures also greatly increase this malfunction. If I start my truck and allow it to idle for 10 mins it's fine, no stalling.

Here are my freeze frame pics from my handheld scanner.

 

Where are you located, is the temp around freezing where you are when you have the symptom?

 

UPDATE: My truck stalls not only when inclined and coming to a stop, but it stalls when I come to an abrupt stop as well.

My temperature here is by 35- and 45,

Suggestions??
