I had problems with the plastic vacuum lines that are connected with the short pieces of rubber lines that have gotten old, hard and are not sealing properly.repaced all connecting pieces made big difference.I have also had the drivers side door locking mechanism leak and replaced for engine would not shut down with key.Passenger side door lock was bad and if I remember correctly I could turn key off and lock driverside door and engine would slowly stop. But I would also look at the rubber. All the other post are excellent and should help you get through this.
