Cylinder #4 has failed. Several mechanics have stated that they see several of these failures with engines equipped or programmed with the active fuel management systems. My engine failure occurred under normal circumstances, 55mph on a farm to market road transitioning from flat roads onto a slight rise when the vehicle started running very noticeably rough. I pulled over and the engine unbalance was very apparent.
