2004 F150 (5.4), Truck has been great. Went on a road trip Saturday to picked up a 5th wheel trailer and no issues during trip. Started up on Sunday and noticed it idling rough and the engine light came on. When accelerating normally, 'misfire' gets worse. If you accell very gradually, the mis is hardly noticable. Power is definitely lacking. Put the reader on today and came up with a P0351 and P0355 (Ignition coil A & E Primary/Secondary Circuit Malfunction). A/C quit at the same time. Not sure if it's coincidence! Any thoughts?
Thanks,
Greg
