Today i was teaching somebody how to drive manual. The person i was teaching stalled the engine about total of 6 times. On the 6th time, i told him to start the car again, the engine started up but then died 1 second later, the check engine light and battery light was on. Then few minutes later i tryed to start the car again, this time i gave the car some gas before dieing, and amazingly the car started fine again. Now i've driven about 30 mins and started the car a few times already, and this problem is not occuring. I"m wondering what is this problem, and how to fix it? Plus, will this develop into something serious.
