Sorry for the delayed response. It is a FWD, and what I mean by hi and low is when you start out typically, the vehicle starts in a higher gear, allowing it to accelerate rapidly. The problem we are having is that sometimes it does not start in that "hi" gear and you have to give it a lot of gas to get going. Kind of like riding a clutch. Thanks for the insight.Do you have an AWD or a FWD Murano? Also, what do you mean by hgh and low gear?
