p0278 #6cylinder contribution/balance
p0335 Crankshaft position sensor A circuit
P0611 Fuel Injector control Module performance

Can someone explain whats going on with my engine, and would these repairs be covered under 100K engine warranty? Also it's starting to use anti-freeze again. No smoke yet,(This Time).Whats your thoughts? EGR Cooler, or Head gasket/head? Truck has 95,000 on it now and if covered by warranty Got to get it in soon. Thanks

 

I cleared codes with my SCT tuner. Engine now has only P0278.

 

I had Ford dealer look at the truck. It appears these codes resulted from blown head gaskets, and a bad glow plug controller. I had ARP studs installed (to save me doing it later),hopefully won't have head gasket issues it the future. When I picked the truck up it was hard to start, checked the DCT's P2552. Still a FICM issue. Took the truck back to dealer, put the laptop on it, and showed no issues. SCT still shows P2552. Any help would be appreciated.
