| Re: How to check for a faulty FPR (Fuel Pressure Regulator) and replace it
Where might I find the FPR on a 4.9L engine, and furthermore, should I even bother? What I mean to say is, was this a N*-specific issue?
I'm trying to pin down whatever may be causing various problems I've been experiencing, including extremely poor milage (<10mpg), a very rough idle (800-1000rpm), and sporadic knocking. |
