Maybe injector problem?

well i bought y 2003 f-250 6.0 a little over a year ago. i have had a lot of power for a long time. but now for some reason it seems i have no power for anything....


Things i have done to it.


I replaced fuel filters, air filter (Blue Mesh), cleaned EGR Valve, replaces egr coolant to coolant hose, little blue one, Took off muffler and cat... then welded cat back in due to emissions... , use diesel 911,,,


what should i be doing to keep up the maintenance on this thing? i am sorry if this si a stupid ? but i am at a loss and cant afford for it to break down on me for not taking care of it. Please help me


Thank you for the help

Are your fuel and oil filters OEM? When was the oil last changed? Have you checked the ficm voltage cold, during a start and after warmed up. What is your battery voltage after all night cold soak with the key off prior to starting and during starting? Do you have any codes?

Also check the oil filter cap and ensure that its OEM as well.

Check FICM volts first. Must be 48V-45V. No less.
