I was told the the 1995 through 1997 were known to have this problem and that 3 computer updates have been available. I was told I had the latest update.

For the last couple years I have returned my 97 LS400 for clunking sensation when accelerating and decelerating. They can't find the problem unless I drive along and then it is very apparent. (imagine that) the tierods and motor mounts have been replaced. Now I am told that it is the normal "throttle lock" problem for the 1997. It did not have it when I bought so how is it normal? The sensation is similar to "play" in a universal joint I think is it is the carrier bearings in the rear suspension but I am told it is a problem in the transmission computer that can not be fixed
