P0191 - All Suggestions Exhausted

Hi there,

got an 04 f150 fx4 5.4 3valve,

Throwing code p0191, been on the website last few days reading all the issues with it,

have replaced the fuel rail pressure sensor

have replaced the fuel pump driver modual behind the spare tire,

Fuel filter replaced with in 3000miles.

Problem still occurs, the EDGE program reads 40psi at idle, on the FRP but when in demand fuel pressure drops to 11 - 8 psi and engine acts as if it were stuck on a rev limiter.

Is there any last options to try before the trip to the stealership??

Thanks in advance

Jeff Stewart

Maybe a clogged sock filter on the fuel pump inside the tank?
