My gramdmother has a 95 850. Yesterday it wouldn't start. It turned over with no loss of power, but it wouldn't fire up. The repair shop she took it to charged her over 0 and said she needed new ignition coil wires, and needed her cap, rotor replaced. But I drove the car the night before and it ran great. No misfire at all! Can someone please tell me if my grandmother got taken by this repair shop. They said the coil wires were 0.
