rough idle, cold start

I'm posting this for a guy I was in the chat room with...
He has an 04 that running rough at start-up, missing and lack of power until it clears up at road speed. Seams to be fine good down the highway. He keeps it plugged in over night in a heated garage. Changed the fuel filter 10K km ago, but one of his friends is having the same problem, and he just did the fuel filter. They're up in Canada.
Shoot some ideas out. I'll try to sucker him into signing up, then we'll have him for good!!!!

Tell him welcome to my world..

It's an injector problem.. my truck does the same thing and has been to the dealer 5 times with no fix.

Ask him if he has had the dealer reflash performed. It's a flash specifically for this issue and better fuel economy. If not try that first.

What year are these trucks?

I also have this problem, intermittently at start up it'll run rough like it's missing, it will have full power and all, but soon as I let off the gas to cruise the tach drops to the idle level and you can feel the miss. Once it warms up it goes away? 2006 model with less than 5k on it.
