Car Begins to Wobble

Feb 1, 2009 at 5:08 AM
I have a new situation. When my car accelerates to a certain speed (not sure what the speed is exactly), it begins to wobble from side to side. It does this for a few seconds and then straightens up, drives a little bit until it accelerates back to the speed, and wobbles again. It's on a planeObject with no other objects in the scene. Has anyone out there in XNA land seen anything like this? I don't have anything crazy going on in my code either. Here is what I'm using the accelerate the car:

            if (keyState.IsKeyDown(Keys.Up) || keyState.IsKeyDown(Keys.Down))
                if (keyState.IsKeyDown(Keys.Up))
                    carObject.Car.Accelerate = 1.0f;
                    carObject.Car.Accelerate = -1.0f;

I'm using the CarObject and JigLibX right out-of-the-box. I haven't done anything to manipulate it other than importing everything into my own test game. The only thing I do is chase the car with a camera. If it will help, I can paste my entire source here for you to look at to verify there's nothing "special" going on that I can see.

Thanks again for any input.
