Well, an update on my problem. Had the tires aligned and balanced.. but car still makes a weird grainy err'ing noise at around 75-85MPH and has a slight vibration coming from the front of the car and alittle but I can feel on the floor. Stops after that or below that. But that's not all. When I began to accelerate from 0 to 15, and some other sporadic speeds, the engine doesn't make the regular noise I'm use to. It has an odd noise. I own a '96 Ford Contour with about 99,000 miles. Does anyone have any ideas on what this is or what I could do? I'm not a car expert, but do you think this might be from one of my spark plugs not sparking and leaving a cylinder idle?
