The last couple of times that I cold started my truck I've been gettin a weird idle. The rail pressure is at 67-7000 then drops to near 5000 kinda like the fuel is gelled. Seems ok at higher RPM but I've been limpin the stock clutch intil I get the new DD put in and the temps have been aroung 50 lately. Does this sould like the CP-3 is gettin weak??

NM, I was informed that the grid heater cycling will cause this. Watched it this morning and sure enough... right when the GH cycles is when it drops for a blip. I feel like a jackwagon

 

Don't worry about it brotha we've all seen everything drop off the first time the grid heater cycles and thought WTF...
