I have this issue with my FBO N54 when I'm accelerating and my RPM will completely drop, but come back up right after. It used to only happen at the track at random times, but now it's happening on daily drives even when i'm not pushing it that hard. I used stg 0 MHD on the track for cooling purposes, but now it really happens on any map, even not on WOT
I checked the datalogs and it seems to be an issue with my rail pressure. I've searched, but haven't seen anyone else with my issue before. In the datalogs, you will see the rail pressure spike up and down to numbers as high as 3500 psi
I've had CEL on startups a few times as it wasn't necessarily a slow crank, but more of a dry crank if that makes any sense. I've gotten a coolant light and/or half CEL from time to time when this happens, but in most cases it goes away without having to turn off the car. A lot of the times I don't get any kind code or light
Just want to figure out exactly whats wrong as my car is just barely drivable at this point. Any help is appreciated, thank you!
