I have this same exact problem...but mine is a 98 with 18,000 miles and mine
has been doing it since about 7,000 miles. And it is still doing it. I
have brought it in many times and they say at the dealer they don't know
what's wrong with it. I called and complained to Chrysler, but they are
still investigating it. I think it is bull shit. I am pretty pissed
about it.
