I have a 03 silverado, every now and then my truck dies on my when i put it from park to drive. usualy one when its cold, even if i let it warm up it still does it. any one got any ideas. Ill try anything, i get tired of having to put one foot on the gas to keep up runnin when im slowing down. Oh i should add, it does drive and idle just fine but as soon as i put it in any gear it just dies. or when im slowing down and let off the gas.
