I have had the occasional hard start and miss in the Spring and Fall after the car has been run and then stopped for a bit. After some puzzling, I have attributed it to winter gas and underhood heat. It seems winter gas is "more gaseous" than summer gas and, in my car, seems to result in vapor lock occasionally. I have never had this occur with summer gas. A smaller diameter non-drop base air filter has helped.
