fuel injectors keep getting clogged how can i clean fuel system?

Assuming injectors are indeed the problem here (?) ... > IF available in your zip code .. Use Chevron Techron fuel with each fill up or Techron as an additive.. Change fuel filter often... If problem repeatedly occurs on same cylinder(s) each time, suggest replacing affected injector(s) .. Injector balance test is bulletproof for finding problematic injectors!! .. Professional scanner and fuel pressure test guage required for performing balance test .. It not a DIY repair ... Them days are over with!

Does it missfire at all like does the truck have a jerking motion with white smoke coming out of tailpipe?
