It may have fouled your plugs, but you can tke them out and clean them. Use a small blade and scrape the carbon off.
You could also take the egr valve off and try to clean it. Use a wire brush. also clean as best you can the passages under the valve, they can get plugged with carbon. Use a new gasket when you bolt the egr valve back down. Keep trying to get the fuel filter off, but the egr cleaning should help.

you need to scan the computer that has a electronic throttle body and a electronic gas pedal one sensor goes bad and the system goes into limp mode

you would need to scan the computer and see what codes you have to start this should still be under factory warr being a 2011 unless you have a lot of miles on it

At 4000 rpm what does your speedo say. Your computer may be limiting both your mph and your rpms. I have a 2004 Ford Ranger at 90 mph the engine sputters and seems to miss. It will stay at 90. In neutral it revs fine. My problem is because of chip programming in the computer. Your problem may be the same.

Did you replace those parts based on the trouble code? Or are you just throwing parts at it? What are the codes?

If You Have A OBD2 Code Reader,It Should Give You A Code And Tell You The Actual Problem,It Almost Sounds Like The Crankshaft Position Sensor Is Not Working Right,That Will Control Your Timing And If It Goes Out,You Will Get The Sputtering And Backfiring.Good Luck....

Can be many things, need to hook it up to scanner.. if u live close to AutoZone or Advance Auto they will check for code free.

first you have to check for code with scanner , sounds like you have sensor problem , (coolant temp sensor map sensor etc). it could be a fuel delivery issue like lean condition . but the code for engine light will guide you in right direction. good luck

Sounds like a bad spark plug or spark plug wire arching out causing an engine misfire.
