I’m having an issue. I went to go to work this morning.
I started driving and the truck was surging. Rail pressure was dropping as it surged. It only would do it down low in the RPMS. Lowest I saw was about 3,800PSI.
Once I got over a certain rpm rail pressure would hold steady above 10K it was decent. At idle my MM3 is desiring 4600K psi and it’s surging from 2500-5000PSI.
I got fuel last night, drove about 50 miles home everything was fine and I turned it off. I’m hoping maybe it’s bad fuel or the filters need to be changed.
Truck is a 2017 with 11K miles tuned and deleted since 2K miles with no issues.
I’ve used Archoil in every tank for the past year as well.
