I have a 00 GTP and have been noticing a slight vibration when going up a steep hill and also a much more pronounced one when at WOT between 45 and 50 mph. I was wondering what this might be and if there is any information I can provide to better diagnose it?
Also, when I am at highway speeds if the road is banking left the wheel wants to go left and when it is banking right the steering wheel wants to right. I am not sure if this is related to the above or not.
The last thing I haven noticed that is a bit off is that my car idles at a higher rpm in neutral than in D while sitting at a light and shifting between D and N while not moving I feel the entire car shudder a little bit. Any idea what this could be?
