2008 F250 injector problems..

First post on here! I recently got a 2008 F250 powerstroke crew cab with 166k miles. When it goes into regen mode it lets out a ton of white smoke!! i had a friend run some codes on it with the snap on scanner and it shows that my injectors are way off from "0" Is there anything i can do besides getting them rebuilt so they will run at "0" mainly worried about injector 2 and 3.

It's possible you have 2 failing injectors. I would be on the lookout for metal in the fuel honestly. I have seen this more often than not when 3 or more injectors start going way out on short fuel trims.

Any base engine concerns like worn out rocker or washed out cylinder walls will also cause fuel trims to go out of normal range.

I understand why you dont want metal in there. Why would injecors if they are failing like you mentioned, three or more cause metal? Thx.

The failing injectors themselves won't cause the metal, however any metal in fuel system from say a failing high pressure fuel pump will definitely cause injectors to fail.
