Paul,
That vehicle and the Bronco II with that engine were known for fuel rail contamination after many years of use. The fuel injectors plug into the fuel rail and we've found many rails rotting on the insides. The rust flakes off and plugs or partially plugs off the injector. We usually replaced the fuel rail and injectores to fix the problem, but you may be able to get away with just the rail itself. Good Luck!
