hello, if the vehicle ran with cable off one would ASUME alternator is ok! however, i bad diode in the aletnator would allow it to charge yet have a massive voltage draw as well, almost all of todays parts stores will do a free starting and charging test for you! ......ps a large voltage drop would rob your ignition of voltage causing your miss!.good luck, marty

Has the stereo been changed recently? If not move to the cigerett lighter. These two are most likely the prob. But you could have a bare wire anywhere grounding out. Good luck and hope you find it.

The check engine light is a warning to let you know something needs your attention to be repaired I would try getting a jump. Could be a bad battery. Lets get the battery charged and tested. Cold weather will stop your car from starting if you have a weak battery. You dont need to tow the car just take the battery to Autozone or Walmart to be charged and tested for cca...cold cranking amps

im not 100% sure if this vehicle has onebut some cars have a neutral safety switch. My jeep had one go bad. If you shut it off, it wouldnt start back up, you had to wait about 45 minutes. Sometime it would start it placed in neutral.
