After putting in the right coolant and oil, drove the car around to get fluids going through the system. When going down a steep grade hill nearby with a stop sign at the end, applied brakes and the red battery light came on (along with a funny burning smell, and also both rpm and mph gauges went to zero.) After we stopped at the sign, we turned the car off then on again to see what would happen. Car had a harder than normal time trying to start up. We went around town to see if its only down a steep grade and tried it again. The Buick only does this when going down a steep grade. Would like to know if its truly an O2 sensor or another cause.
have the same problem?
