Buzz test & Cylinder Compensation rest.

[Hillbillyshakespeare]

I got FORscan today and performed a buzz test and cylinder compensation test on the injectors and checked the DTC’s on my 98 E350. I believe it’s a safe bet to say that the under valve cover harness has come loose or is faulty. Injectors 1, 7, & 8 for sure are not as sharp as the rest. Any Powerstroke guru’s our there that could give me a little more insight? Here’s a link to the buzz test video.

You won’t know for sure unless you pull the gasket and UVCH and ohm them for resistance. I don’t know the numbers off the top of my head but they’re an easy google search away. If everything ohms okay you’ll want so swap the injector with another and see if the error code follows the injector.
