I have a 2009 Ford Focus and my car (and I've heard some other Fords from around those years) and it kind of revs up a little when idle, even when I'm not doing anything. Does anyone with a similar car have this problem? I took it in and the mechanic said there's no fix and it's normal. Also, I have Sync on the car and it's been really finicky lately (I know it's five years old, but still, not that old!) and will just not play songs, skip songs in the middle, or not play anything. Would love to know if others have these problems!
