Hi everyone I got a very hard situation I can't figure out but first I want to tell you everything that is done I own a 2003 dodge cummins 5.9 6 speed manual the motor was just rebuilt about 10,000k ago it has 60hp bd injectors and a fass fuel system with a superb turbo and all brand new when I put the motor in and am running a bully dog triple pup for a chip ok now that I think is close to everything.
So now when my truck is at a idle it seems like it bogs then ticks like ifi was starting in a high gear at a dead stop (the rpms do not move when it does this) but only does it for about 2 seconds then it goes back to normal but it contuesly does it so I did plug it in and at a shop and the fuel rail pressure drops off wen it happens then spikes right back up so I'm really wondering what the hell is going on please help me
