The 2 times my truck has been in for warranty work and there was injector issues, there was no codes that lead to injector failure. You have to buzz them and see what ones look like there are failing.

What is a BUZZ test
|
|

|
when you run a diag on a 7.3 or 6.0 for the injectors it will make a buzz sound there for buzz test

We buzz tested mine using a Snap-On obd 2 commercial shop unit, it gave no codes on the initial scan, and also said the injectors passed the buzz test. #6 injector was bad the whole time, the ford dealer's computer found it on the second try. The snap-on might have after a couple try's but it didn't the first time.
There was a 3 day gap between trying the snap-on first, then taking it to the dealer today, but the symptoms were the exact same the whole time... Just figured I'd put that out there, the buzz test apparently isn't foolproof. |
