I don’t understand everything you wrote, but it would help to know:

what codes are there?

has the fpdm been replaced? Have you inspected it ?

 

Does it only shutter at idle and run fine when the rpms are up? Stalling at all?

 

truck shakes and stutters like it suffocating from no gas.I changed fuel filters,all the plugs and added fuel injector cleaner.it still stutters.codes read bank#5 before i changed the plug.fpmd changed july 2017.ill check it out,scan code.

 

shutters when driving,idle,slow or speeding up,etc.
