Hello Scotty I have a 97 Ford Ranger 2.3 l two wheel drive 171000 miles but I have poor idle stalling hesitation I have changed mass air flow sensor oxygen sensors clean the throttle body new catalytic converter and now a new fuel pump it was saying at the Schrader valve 25 lb Now new fuel pump 75 lb why am I having the poor idle and hesitation? If you can please help me thank you

75 lbs is waay too much pressure, perhaps you need a new fuel pressure regulator too
