    It could be many things, unfortunately and without experiencing the problem first hand or being able to do some basic diagnostic tests its hard to say. It could be a transmission problem, could be oxygen sensor related, a vacuum leak (but I don't think so at cruise intake manifold vacuum is low). Too hard to guess without being able to drive the car
