My car was running fine then all of sudden it started lugging out. When I would stop at the red light it would hardly run, it would chug along then all of a sudden it would pick up speed just fine then if I came to another stop it would do the same thing. It started backfiring and then it would not go over 5 mph. It would just chug along. I need help I havent even had it a month. I can't understand how it would start running so bad so quickly. I don't drive it hard or anything like that. So I haven't abused it. Please help.
