So I have 2011 f250 6.7
I have replaced my pcm,
fuel rail pressure sensor, fuel rail regulator, lower pressure fuel lifter, filters.
I am still getting the p0193 circuit high bank 1, with rough idle and shut down issues after it is warm.
I am thinking it is a ground or bad wire harness. should I start at the pressure sensor wires with the multi meter or should I start somewhere else? been Months with this bugger in and out of the shop. any help would be appreciated
