Trucks a 06 with ats dual fueler, 100% over exergy's, single 467. Couple of months ago every blue moon the truck would have a fluctuation in RP. Would clear up and run great. Ended up having my injectors sent out due to a bad stator o ring, came back and the issue was still there. The last few weeks it has gotten to the point the truck runs perfect until it reaches full temp, after that the rough running fluctuation in RP sets in. Changed my controller to a new working controller off another truck and non change. Even bypassed the controller and had my tuner write a tune for it and still no change. Now the truck will only run if I unplug the RP sensor and Max rail pressure. Plug it in and I only see 19-2000psi cranking. Unplug one fca at a time or unplug them both and no change. Changed the PRV out with no change. Also only codes I'm seeing is p2127 apps 2 circuit low, p0652 sensor reference voltage low, and sometimes a p0251 injection pump fuel valve feedback. Any ideas?
