Codes are just starting points. I had a 3.6 throwing a intermittent cam sensor circuit code and it was the oil filter bypass valve in the filter housing jiffy lube broke when doing the oil change. Granted newer car with vvt but just making a point about codes.
Imo you need to find somebody or shop that are good with an oscilloscope. Dealers for the most part dont train or use them. Then you will actually know what is being put out to the pcm. Can compare to known goods and go from there.
