Need some help!
Hi there im new here and new to Super Dutys but i love them! Altho mine is not being so nice. It has the 5.4 in it. When its idling it has a stumble to its idle with a pop every now and then out the exhaust. It revs fine when its first started. If i pull out on to the road and start away easy its ok a slight miss but if i put the throtle down its just falls on its face. But if i get it up to crusing speed its ok as well. But even at crusing speed more then 1/8 throtle and it starts missing and falling on its face. Any ideas what it could be? It smells like its running lean as well.

I am an experienced mech/ tec just not with these trucks. I figured id hope on here and see if any of you had experienced the same or similar issue and had a fix for it. I changed the fuel filter and the exhaust is cat-less with a glasspack so its open. the front 4 coils are yellow (unknow brand) and the back 4 motorcraft. Not sure when the last time the plugs were changed, but again I fell its starving for fuel. It feels like all the cylinders not jsut an isolated issue. Maybe the Fuel control module? Dose it even have one? Thanks again for all the help!
