- 1991 Explorer Eddie BAuer
new to site been reading the threads for a while now, i have a 91 explorer, rough idle, no hesitation, new plugs, wires, fuel filter, injector cleaner ran through many times, i run it only on supreme gas, no CEL codes, the only thing i don't know is if the fuel pressure regulator is causing the problem, when i bought the ex, it wasn't running, i got a pressure reg. off a 93, had to change the fitting from the plastic, snap on one to the screw on one, was wondering if the pressure regulator on the 93 had different pressure rating than the 91, i can't seem to find any info on this
