This to is my first car and its already being a pain. I'm not sure whats wrong with it. I was driving it along and the RMPs dropped quickly, and the car shut-off. 5 mins. later the car started right back up again. I got it home, it seems to me if i got it up past 3500 RPMS it would shut-off. We replaced the fuel filter and now it won't start up. Could it just be ice in the line or bad gas??? I'm open for suggestions.
