Shudder and vibration problem

[neuropsych]

I always use 91 octane gas and have a vibration problem since I left the lot last month. I also have a vibration/shudder when the car decelerates between 12 to 10 mph. The dealer told me to break it in. 1500 miles later and it still does it. Does anyone have this other shudder? I have driven other tsx's at dealer and loaners. Some have it, other's do not. They are trying to figure it out, but they say that it is a quirck of the car. If the car that I test drove did this, I would not have bought one. I use Chevron or Amoco 91. Does anyone have better results with another gas company?

Thanks

Is your car manual or auto?

It is an automatic. I am wondering if the 2006 model has this problem because of the increase in horsepower?
