Does anyone have any idea of what might be going on with my 2007 Ford Fusion? Occasionally as I'm driving, I feel something in the accelerator like a loss of power and then the wrench light comes on. I have pulled the car over, turned it off, and restarted it and it is fine for a while. This usually just happens at highway speeds, and very rarely just driving around town. A couple of times the check engine light will come on at the same time, but will go off after a day or two. I am planning on taking it into the shop pretty soon, but am curious about what it could be. Any information would be appreciated!!
