Engine stutter and weak throttle

[barneys raptor]

They did change the oil and marked the dipstick, had me come back in 90 days, re-checked the dipstick and told me I was good to go. Is 21B10 related to the cam phaser rattle on startup? That is still open, when i inquired with the dealer after i got the letter, they did not recommend doing it because of reports it was causing another issue.

Did you add oil during that 90 days? If you’re going through 2 quarts every 4-6 weeks, that must be more than a quart every 3k miles.

21B10 is the new software to prevent cam phaser rattle; it should definitely be completed. Dealers shouldn’t be making up their own repair direction. If there is an issue after 21B10, there is a second bulletin to address it.

FordTechOne I was told by the tech at my dealership, Ford said don't install the new software from cam phaser rattle because it was causing other issues. Am I missing something?

I didn’t add any oil during the 90 day consumption test period. Since my last service I put 4,851 miles on the truck and I’ve added 4 quarts. Dipstick is reading full. If my math is right that’s about 1,212 miles per quart.

ReconReggie, they told me the same thing but I’m going to push them on it tomorrow based on fordtechone’s feedback. Possible they just didn’t feel like doing the work although I thought they got reimbursed by Ford on these.

That was in early 2021. There hasn’t been an issue since Supplement #2 was released July 2021.
