I got a 2007 f150 5.4 triton motor 94000 miles all stock just gots mod k&n filter top end rebuilt due to cam phasers and timing guides for the past year when i make a real sudden stop or sometimes quick turn the truck will bog a bit the i give it gas and will drop to 100 rpms and if i keep my foot on the gas the truck will die if i keep my foot off the gas it will keep rolling then die after attempting to accelerate fuel pump driver module is in good shape with spacers the old code i get when this happens is p0191 for fuel rail pressure sensor although i just replaced that what could it be?

 

Anyone i need to nab this down
