starts a bit rough, idles okay when warms , when reving it acts like a misfire or starved for fuel I checked the headgasket, it is fine (held 15lbs for 15 min before I unhooked the tester) , I am being told fuel pump , wires plugs, coil pack weak.. Does anyone know anything about these 3.8 Mustangs other than the obviouse "they are junk" . I am going to do the simple things like fuel filter first then plugs and wires.. but would like to pinpoint the problem before wasting $1000 thanx
