same thing happened to me when i started my car and i still don't know how the car was in gear,as i always keep it in neutral and always use the e brake.Anyways,so it stalled and the wrench light came on.The car went into limp mode and ran like shit till i reached home.15 min drive.So turned it off and started it back up after like 10 mins and the it was back to normal.No more light.
