2 weeks ago I purchased a 2011 F250 with the 6.2l. I love the truck! It has 31000 miles on it. 2 days ago it started running like crap and the engine light came on. I put my code reader to it and it came up with PO351 so I googled that and it said coil. I went to my Ford dealer and they seamed quite surprised about it. They told me my warranty would cover it. I guess my question is, has anyone else had this problem. I'm taking in on 9-30-13 to have it checked out and I'll post what the dealer figures out.
