Misfire on dod cylinders

[Bjbmacon]

Guys I’m fooling with a truck the guy says he deleted dod but he didn’t program it out of the computer. Now it has misfires on those cylinders. Can it be misfiring bc the solenoids are not being detected. Causing it to shut down those coils and injectors?

What all did he do when he “deleted dod”?

If he didn't remove AFM from the programming, it's gonna have misfires and all kinds of DTCs.

We know of at least one thing he didn't do. As @wjburken asked, what all did he do?

He said he replaced cam with non dod cam and lifters.

Did he also swap out the VLOM with a non-dod plate?

What about the VVT cam phaser?

What are you driving or working on?

If this were in my driveway, I'd first drive it around in manual mode so that AFM is not active and see if the misfires go away. Then I'd with BlackBear to tune it as I have no idea what kind of camshaft is in it.

The VLOM under the black plastic intake manifold ought to have been changed for the delete, but often is not. I ought to be smooth and not lumpy.

Ask for receipts or details on what parts were used.

Until AFM/DOD is tuned out, I am fairly certain that the vehicle will need to "see" the old VLOM or it will give you problems, regardless of being in M5 or not.
