Porsche 356 Super 90 Problems?
 

I just bought this car from Germany about a couple of months ago, haven't had time to drive it. Though today when I drove it for the first time, there was a terrible vibration in the steering wheel, it was so bad I'm actually am afraid to drive it now, the whole car was wobbling back in forth on the highway(this was at about 70KMH) plus the Launch X431 PAD isn't working, the needle just is stuck at zero despite the engine being revved, what can be done?? This car is a big investment on my part! Plus I don't want to wreck it!
