my brain has melted!!!! P0308 code

<HR style="BACKGROUND-COLOR: #dddddd; COLOR: #dddddd" SIZE=1> <!-- / icon and title --><!-- message -->
I have a 2007 F150 5.4 it has a P0308 code I have put a new set of coils all 8, plugs all 8, injectors all 8, and a new upper intake complete assembly.

after no change I swaped the #8 one at a time the coil, plug, and injector with #1 and the P0308 code always comes back within 5 miles

the truck runs amazing as long as your not in high gear at 40mph -65mph if so it goes to shaking and jerking

has anyone has this issue and found a resolution, Thanks

Have you checked compression on that cylinder?

Almost sounds like a piston ring.

I have the same problem. New cop new plug new injector. I'm beginning to think the cat may be bad. I hear a rattling and get a funny smell now. It runs so good at idle and with no load but just stumbles when it has a load. It's frustrating.
