Not related to your deletes likely.

Typically means the HPFP is going for a poop.

There is a reflash from Ford to correct this, but I have been told it's not very effective. Been out of the Ford repair world for a couple years now.

I talked to someone at Gear Box where the tunner came from and they said they were having this issue and was testing a fix now and should have it by the end of the week. crossing my fingers. The truck was fine until i put these deltes on never got any codes at all. started this about 40 miles after i put it back on the road. also it does fine pretty much all day until the air temp outside gets hot. For sure runs better until it starts messing up. Thanks for replying

So they are likely using a very old calibration in their flash tool.
