2003 silverado rough cold starting problem
 

Hello I'am new to the forum, i have a 2003 silverado with 6.0 that i just recently purchased. When i go to start it when it is 40 degrees or below the truck has a rough idle and wants to die. When it is warmed up it runs great not sure where to start. Any advise would be greatly appreciated Thanks!!!

Sounds like a good throttle body cleaning and some plugs and wires would do you good. I think its anything more than that.
