Serial: 2B229711. Posting for a friend. A few months back the motor would cutout bad. Used a timing light to determine cylinders 1 and3 were not firing so he took it in to get it looked at. Long story short they only replaced one coil pack said one bad one can effect both and after 3 trips its doing it again. Seemed odd to me about just replacing one just looking for any more info or feedback thanks!
