Keep getting a P0191 dtc after 100 mi drive or so.
Otherwise, engine seems to run fine, no suttering, no hesitancy on start etc.
But the fuel rail pressure sensor is expensive .
The only thing I can find wrong is that the evmv line from the vapor management valve to the engine looks soft and spongy at the curve in the line.The hose had a tag 9D289-CC, but this hose apparently does not exist at Ford, even though it is printed on a tag that says ford. So I do not know how to replace it. Could this hose collapse? would it cause a P0191?
