I have done diagnostic testing, and have replaced
the parts that it said were bad did another
diagnostic test and it's saying the same thing, my
question is, is likely that the PCM has gone bad?
Whats the list of DTC codes? 4.6 or 5.4? what are the symptoms? the computer is least likely issue.. withhout more info.
It's a 4.6
Like Auto_Centric asked what parts did you replace ?
Most DTCs do not indicate which parts to change, only system to be checked, which may be many.
