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.
It could also be a bad plug. Both will throw the same code.
Either way, I wouldn't worry about it as long as they fix it and the issue doesn't reoccur. Sometimes you just get a bad coil/plug. I had an Escape that killed a coil at 40,000 miles for no reason. After that it was fine until I got rid of it at 150,000.
Took the truck in today. Definitely #1 cylinder is not firing. Good compression in all 8 cylinders. The worse news is oil in my coolent. So far they are not sure why. It might be bad oil cooler, cracked head, or cracked block. Now really hoping warranty will take care of it. I'll keep posting updates just for fun.
