EGR valve or Sticking VGT vanes?

Hello everyone, recently I have been having a reduction in gas mileage and sometimes when I floor it I roll coal. My friend and I decided to pull my EGR valve and we discovered the bottom o-ring was busted and it was covered in soot so we went and got a temporary fix o ring from autozone and put it on the valve after we cleaned it off (I plan on going to ford and buying the req. O-rings). The valve was unplugged and things began getting better such I was getting 15.5 mpg in the city (haven't done much highway driving since we fixed it). Well yesterday it was back to the way it was again (12 mpg city-14 hwy). The possibilities were the EGR valve, sticking turbo, or exhaust leak. I eliminated exhaust leak because I don't smell any in the cab nor do I hear a whistling sound at idle. As for a sticking turbo I don't really know the symptoms of that other than it sometimes makes a thump noise and I haven't heard any of that plus I haven't noted any over boosting from my ScangaugeII.

Need some help here please

When was the last time you checked your air filter? The 6.0 filters are awesome but not bullet proof. If your truck has stuck vanes it's probably going to be really laggy as a symptom. Could also be a dirty MAF sensor, or a boost leak if your truck has the plastic cold pipe check under the air filter they commonly rub on the box and gets a hole in it.

I replaced my air filter at 202k and I'm now at 205k. I checked my air filter last week when we pulled and cleaned the EGR valve. The bottom o-ring was damaged so I went to autozone and bought a temporary fix
O-ring which it got a little better but now it's back to what it was doing. Went and bought the Ford EGR gasket kit today, gonna put it on this weekend and we will see what it does. Hopefully that will fix it.

Great! I pulled my egr and same thing, dirty as ever. Cleaned it up and replaced both o-rings. Took it for a drive on the highway and so far, it's not sputtering like it was yesterday. Hopefully that was my problem and not the turbo. Thank you!
