My car has been stumbing when I am in top of third and in four. TOday I was going to work and I was driveing quick. The car was ranning rouf and that stumbing was there. I then hit a light and at that light I have to turn. So i do and the car turn off. I pulled over and tried to turn it on. It does not want to start no more. Someone told me that the stumbing was do to the cam sensor and now with the no start I am strongly thinking it is the cam sensor. What do you guys think.
