Here is the latest of what we are seeing at the dealers on this issue. If yours is having these issues which may be intermittent take a close look at the items listed. Also this is a ongoing issue which Ford Engineers are still going after. There are a few fuel injector issues but not many it all seems to be on the ignition side of things and the water in the intake from the intercooler is a whole other issue they are still working on and I go over the latest design on that as well. The new issue with age on these is spark plug cracks something so small will likely go overlooked by the technician or DIY type and they usually cause intermittent misfires like this one. It is something to look at if you are having any of these ongoing issues......

 

Man oh man Youtube cut off last 3 min of video, I re uploaded it and relinked the full video now, sorry about the last one and how it just cut off at the end.

 

Ford's never had good luck with plugs. Anyone remember the old 5.4L 3 valve plugs? It's odd how even Autolite (whose plugs I REALLY don't like) made a one piece plug.

 

Oh yeah I made a whole video series on it, one day all the trucks will have the new revised plug in them and we will be past that.........one day.
