I hope your now satisfied with the car this was not a normal issue, a slight back fire during start up only without any trouble codes was a difficult diagnosis since the car did this intermitantly" After recording a movie of the data more the 14 times and comparing data we found where cylinder #3 was receiving more then signal to fire only during a start, we found a defective ignition module was the culprite! We hope our efforts has proven worthy of your continued faith in Magic Mechanic!
Car is going back for more diagnosis when a loaner becomes available.
