I have seen this many times. What we do is a top engine clean/decarbonization. Carbon builup on the valves causes what you describe and is usually only affected in cold weather. We use GM top engine cleaner and follow it up with techron in the tank. Sometimes takes 2 treatments but we have fixed about 20 cars with that procedure. Good luck.
