    My 200q20v behaved just like your description, Denis, when I got a load of
    bad gas at a station on the turnpike while I was driving from Michigan to
    Pennsylvania last summer.  Several treatments with the kind of gasline
    antifreeze that absorbs water cleared up the missing/stalling under
    acceleration.  Thanks to Steve Bednarski (I want your car, Steve), I got
    the thing running well enough to get back home.  It  took two tanksful of
    gas with the antifreeze to eliminate the misbehavior completely.
