Answer 3

Very simple really. There is something wrong with the way it runs. There are sensors that control various aspects of how your engine runs and chances are one of those sensors detected a problem or a sensor failed. We, out here in the rest of the world are not able to read minds or diagnose an engine problem without an item called a scan tool. Have it checked out by someone that does that. They are called automotive technicians, and yes you have to pay them. The required tool cost a lot of money and they just don`t do it for nothing. Or you can hit up Autozone and see what kind of nonsense they tell you
