I have red the question of yours car, I am having the same problem, while driving on gas and also gasoline, when I am driving normaly on one speed it starts to shake, when I take off the speed it stops to shake or when I make my car drive faster it also stops to shake..
I am havin this problem for more than a year I guess, my car is made on 2004 december.
So the reason why am I writing - is to ask you - have you got trough the problem and maybe you can help me to solve my car by saying what was wrongg on your car..
also mechanics cant say whats the problem - they just cant find it - the car is in absolutely good condition.
I have drived to chrysler centre (in Latvia, thats the country where I live) and they said that I need to change cardan (I hope you do understand the meaning), so I changed it - and nothing changes..
Waiting to hear from you some kind of info, please dont hestitate to reply.
