Code 91 is a neutral safety switch, the other is cruise control vent solenoid. If you 've replaced thewitch and your light keeps going on andoff then you need to find the short in the circuit or it's a bad pcm or connection. Due to the age of hte car i'd think there is a short in the harness, look for frayed/chafed harness someplace coming in to the car.
