P0113 Intake air temp sensor or circuit open.
p1119 Again, an intake air temp sensor or circuit open.
P0475 Exhaust Backpressure Valve malfunction (could be bad sensor or plugged pressure tube).
P1211 Not an issue. Normal for a chipped 7.3L
P0541 Intake air heater malfunction. Not an issue.
On the buzz test the last 2 buzzes were dull in sound and not as fast as the others.
On contribution test, got these codes.
P0269 #3 contribution
P0284 #8 contribution
P0541 Intake Air heater (no problem)
P0640 Intake air heater (no problem)
It sounds like the back 2 injectors are bad, correct?
But, codes come up as #3 and #8 aren't contributing as much?
So what do I do from here?
Do I need to do more tests?
Thanks

If you have a gray-colored camshaft position sensor, then #3 and #8 usually fail the CCT. It's just the nature of the beast.
Don't sweat the P1211 as it's normal for a chipped 7.3L to set this code after a hard run in a "hot" tune.
Also, the P0541 isn't important as it just shows up because of an intake air heater delete or disconnect. It IS a problem if you still have the heater and wiring intact.
