My mothers 1995 Oldsmobile Aurora is stalling while cruising down the road. I put it in neutral and start it up again and we keep going but its not the way we want to drive. It also is accelarating randomly, as if the cruise control was set and it needed to speed up. In addition the radio, which has a control on the steering wheel is randomly increasing the volume to very very loud. Is this car possessed? Could all of these issues be related? Should I get rid of it? It only has 60,000 miles on it and the interior and body are in pretty good condition. Help
