I have a 2010 Ford Edge and have noticed an intermitent problem when starting. Usually it starts right up, but sometimes after the engine is warm and I have parked for about 20 minutes or so I go to start the car and it takes a few more seconds for the engine to turn over. It is really hard to describe but don't think this is normal. Has anyone else experienced this? I have been using high Octane gas in it, I don't know if this could be doing it.
