hi i have a 2001 gmc 1500 sierra 4 wheel drive in cold weather when i start
the truck in the morning the engine races very high then it idles very
rough and shuts off it will start fine again but continue to do the same
thing until the motor completely warms up when the temperature is above
freezing the vechile works fine -any ideas.
What engine do you have ? 6.0 gas ?? If you find out what the problem
is can you please post it. I have the same problem and I am thinking it's
fuel injectors. Also do you ever use throttle body cleaner on this truck
