My Mystique with 76K miles has the same problem.
I have yet to find a solution.
I do, however, have a question.
Won't significant engine misfiring result in a CEL?
To me, this eliminates the ignition system as the source of the problem.
Early flooding problems with the car seven years ago and subsequent misfires would always trigger a CEL. The light would clear by itself after a day or two.
Comments?
