Getting a very random miss or hiccup at idle, rail pressure will drop from 5.1 to 5.0kpsi every time it does it (im sure its dropping father than that but the miss is so quick i think the edge barely catches it). It will also start missing around 1800-1850 rpms while accelerating with a tune 200hp or bigger. BUT when it gets to 1900 or more rpms it runs normal, its just that 1800rpm range. WOT runs like top. It did have a p2291 I cleared it a few days ago and it hasn’t come back, Im leaning towards the hfcm acting up but was curious what you guys think?

Truck info- 2008 6.4 with 59k miles. Full dirleets with gdp Ndash.

P.s. Fuel filters were just changed a couple days ago, didnt affect the miss.

Just a little update for those of you who might encounter this same issue. Replaced the factory pump with an airdog and it hasn’t missed since.
