4.0 v6 4x4, it doesnt idle right when you first start it in cold weater, it runs really rough and you have to hold the gas down or it will cut off. It does this every morning, I changed the idol air control valve and it still does not work. When ever it is running rough and I hold the gas down enough to keep it running the exhaust makes kind of a small popping sound i dont know if that helps. I dont know whats wrong with it but it only does it in the morning when its freezing out side. What could this be?
