6.4 feul rail pressure sensor
i got a 2008 6.4 liter and when at idel the rpm is all over and no power ,buckin, misfire,etc...The Ids VCM first put 4 faults up,2 for feul rail pressure sensor and feul regulator and the other 2 was clogged DPF and the VCM would not let me do a manual regen. I took off and clean DPF and at first I taught it was fine and then about 15 mins into test drive it went back too square 1. The only 2 faults that are up now are the feul codes. what do someone think and where is the pressure sensor, in top pan?
