Question about 1997 Buick LeSabre
There is a reason, it's just not obvious. Did you by chance take it in to see if the car has any codes? This would give you an idea of what is not working properly. For some reason the computer is getting the wrong signal from one or more sensors, perhaps a bad connection or a sensor going bad. The most obvious sensor to me is the A/C. Any time you turn that on, the engine automatically revs up to handle the load from the compressor but other ones could be creating the problem. Resetting the computer would be a dealer option if it can be done because it would involve putting the car on their computer to do this. Hope this helps,.
