The thing is that the CP4 has been a piece of junk since Ford starting using them. The only real solution is for Ford to design a completely new fuel pump that is not susceptible to failure due to little to no lubrication that today's diesel fuel provides. I use an additive to help that, but it's not really a complete solution.

 

If I remember correctly, it was a OTA update. It may have updated while you were at home and removed itself from the recall list once it was finished.

 

For those who’ve put their truck on a Jenny Craig plan do OTA updates mess with the custom tune?
