Alright, I have been fighting random misfire issues for the last 1.5yr since I got this truck. So I replaced the entire fuel system that was in the truck to rule out any issues. System is now setup in the following manner:
20g Summit fuel cell
100 micron pre filter
DW350iL pump
10 micron post filter
Aeromotive FPR 12" after the above post filter mounted on bed frame (Vacuum reference hooked up from intake manifold)
-8an return to cell from FPR at bed rail
-8an feed to billet rails
Stock injectors
E-fans programmed
Everything else on the truck is stock, down to the air filter. Below is a scan after I installed the new FP, which fixed my previous fuel pressure issues. It is now dialed in at 58psi idle. Then here is a scan after I took the truck for a 1mile drive down the road. This was a slow cruise, I did not beat on it at all in that mile. I am lost as to what would basically net 2 dead cylinders after a mile drive. Truck ran great until I took it for a short drive, now its acting like it doesnt want to run... I was charging my laptop when I took the truck on maiden voyage, so I do not have a log of the drive
