Hello and welcome to JustAnswer!

If you have one coil not firing and the coil has been ruled out then you most likely have a coil driver issue but it could be cam timing related. Odds are the driver wire is either open or the driver within the powertrain control module has failed.

Have you checked for fault codes?
