The vehicle suddenly accelerated and then slowed down rapidly. Pulled over and put car in park and turned it off. Called my uncle who is a mechanic and was not to sure as to what could have happened since he was not there. Started car and reved the engine to see if anything unsafe happend. Car seemed ok and was able to drive it home. Mechanic looked at it the next day but could not find anything wrong he said or duplicate the problem.
