On cold mornings the first time you start truck for the day it's hard to start. After the initial start up the truck runs perfect the rest of the day. When warm weather is outside the problem decreases.
So far the chevy garage has tuned up the truck, checked fuel pressure, cleaned the throttle body, installed mass senor, when mass sensor was replaced it helped about 50% better.
