car problem
last night my car was working fine and i was getting out of my friends drive way when all of a sudden my car started to jerk and it just died, i tried to start it again and it did but when i gave it gas the rpms didnt go past 2 when i would rev it. so next i used jumper cables and my car has been working fine ever since it starts , it runs, i seem to have no issue with it whats happening?
