|  cobalt problems
so my girls car has been acting up for about a year now (2005 chevy cobalt base model), it does it randomly and to different severity. usually about once every 3 months for a day or two, but still random throughout the day. it seems to only happen when idling or going in reverse. one time it tripped a random multiple cylender misfire code and would not start for 15 min. after the car is shut off the code clears. i took it to a shop and they said it ran fine all day and they couldnt find ANYTHING wrong with it, not 2 hours after it died in an inersection. i also got the same thing from a different mechanic. i replaced the plugs and wires last summer and it still does it. regular oil changes, used the injector cleaner every few tanks for a couple months and it didnt help, no odd guage readings, just randomly happens.

i got a vid of what it sounds like, and also i saw the check engin light fashing while this was happening, shut the car off, it started up with a light sputter with no code and she drove off w/o a problem.
if anyone has any clue on a good spot to start that would be very helpful, the list of things that could cause this from my research range from a bad fuel pump to a loose ground wire on the top of the transmition case. (about 54 posible causes from the list i got)
