I'm leaking gas from engine when it sits also I have little power when I hit the gas. Im not sure if it's just a bad O ring or if it's the injectors themselves. If it is the injectors any tips on replacing them and any recommended injectors?

The '90 - '95 4.* liter engines are equipped with a sequential Port Fuel Injection (PFI) system. The Sequential Port Fuel Injection system replaces the Throttle Body Injection (TBI) system used in previous years. The PFI system replaces the two injectors in the throttle body with eight injectors located in the intake manifold. There is one injector above each intake valve. A fuel rail distributes fuel to each of the injectors.
