Buddies truck acting up

[C-WAY]

My friend 04 6.0 reg Cab 2500 HD is acting up and kind of sputters when accelerating and barely will idle in Drive. I hooked my PLX up to it and the all the ST and LT bank ratios were at zero and not moving, both in drive and idle. and I noticed my percentages would go back and forth from around 0 to 5 to -3 and what not... (Dont know if thats an issue or just stock percentages) He was told it could be sensors in the intake manifold or a Throttlebody issue so I let him use the whole truck Manifold and TB setup off of my 4.8 to see what happens. I was thinking it maybe could be bad injectors? Hes gonna swap the setup this weekend and see what happens. The truck has no DTCs being thrown out either

The Truck used to be a Window Delievery truck here at work and has 111,000 to the clock and the former driver used to have a really heavy foot and abuse it before we got a newer truck.

Most times that's a dirty MAF and throttle bore. Need more info.

Ill let you know more info tommorow when he installs it. Ill tell him to buy that MAF cleaner as well.

you may want to check your 02 sensors as well

Might want to check all of your fuses (2 - 15amp run the sensors) or your wiring to your sensors sense they are not responding.
