I have changed many parts on my 2010 Ford Focus se 2. 0 and has not changed anything. I started out with not idling and after spending a few hundred dollars it has not changed anything. Very dangerous. When you come to a stop it shuts off. The person behind you thinks your going to proceed and you don't do to car shut off it is a very dangerous position your in. I did read that there are many of theses mystery problems with theses vehicles and Ford cant even figure it out. If this is a safety issue with many than why has this not been corrected by Ford. Does so many people have to be hurt before it becomes a recall? I have also heard that this happens under warranty and up to 100k. Verry sorry!.
