These codes are new to me . We are just starting to see these i have 2013 f150. 3.5 turbo . P2306 and p2309 are stored . Both cylinders 3 and 4 are not firing . Swapped both coils with known good coils and no change. Customer has changed all 6 plugs and 1 coil before he left it with me to check. I am needing a wiring diagram . Any input would help. Thank in advance.
