My 1992 grand marquise keeps shuting down on me when l hit the brakes or when l make left or right turns,or when l use the windshield wipers? Sometimes when l first start the car it will lose all power and memory,but l just wanna know why it stalls when l hit the brakes or make turns.The car been very good to me but this is the only problem it has.

Have you thought of asking the mechanic at your local Service Station?

Hi, my daughter Valarie had a similar problem about a month ago. Take your car by either AutoZone or O'Riellys and have them hook up the free sensor and it will tell you exactly what is going on. With Val is car it was just her oxygen sensor that was doing exact same thing that you described. It is free to have the sensor check done so if l were you I'd have it checked. YOUR FRIEND LISA

I'd recommend throughly cleaning the battery terminals: remove both cables, and clean them with a little water and baking soda, then scuff the surfaces with fine sandpaper.
