Power Loss

[Shady601]

Hello everyone ! I come to you because I have a small problem with my 2020 Ranger Raptor. I had a gradual loss of power a few weeks ago, we checked with the mechanic and he checked after going through the suitcase and the tests usage that the EGR valve needed to be replaced. So we changed the valve but on the other hand, I have the impression that the car has not regained all its power and while doing research on the internet, I found an article on carbon which clogs the engine. So, I wonder if this could be the cause since everything concerning the EGR valve has been adjusted.

Does this have the 2.3?
If so the EGR Valve has been misdiagnosed many times - parts shotgun at the truck
It is the DPFE sensor that has failed, it sends false information to the EGR valve and the DPFE Sensor will not throw a code unless it is in full failure.
