Re: Misfire on c and e left bank
common problems are spit out rocker arms, if your exhaust valves are not opening it will still suck air and create compression but wont operate. If you pull the even bank valve cover off you would clearly see the rockers laying in the head if this is the case. IF this is the case it is due to other issues, possible valve seat, valves sticking in the guides...
Other common issues (not as common on those exact cylinders, I usually see them on the corner cylinders, 1,2,7,8) but head gasket issues are very common on the 4.7l... If it has been run hot 1 time and ONLY 1 time it has likely blown a head gasket.
