So i have a 2011 expedition about 125k miles on it. Had it for a little over a year. Love the truck. Ive put about 25k miles on it. It developed a slight miss or tiny stumble on a 2k mile road trip about 8 months ago thats never gone away.
I have a slight miss at cruise at almost any speed and the engine is not fluid through the rpm range if i get in it. The miss is barely noticeable most of the time but when i lean on the throttle before and after the first shift its a little more noticeable.
Sometimes the idle is a bit rough, i thought that was pretty normal though for the 5.4.
No check engine light, very few misfires here and there on random cylinders with my torque pro scanner. Nothing on forscan.
I have done the following maintenance / repairs (the miss has never improved or gotten worse during any of this)
New OE plugs from ford (no fakes lol)
MSD street fighter coils
Changed all fluids (engine oil, power steering, transmission, rear axle, coolant and brakes)
Full Timing set with ford parts
M360hv oil pump
New thermostat, radiator cap and water pump
I run penzoil 5w30 ultra
New battery
Any ideas? Not sure where to look next, possibly injectors? I took it to a local shop, they could feel what i was talking about but couldnt find anything wrong.
