'93 tbi 5.7 Feel like im just talking to myself in the other post and I wanted to start a new one since I have narrowed down my fuel consumption problem. My fuel injectors have been dumping waay too much gas at idle and throughout driving causing horrible fuel mileage. I have taken apart my throttle body and replaced the fuel pressure regulator diaphram; the injectors look spotless. After this my spray seems a bit more normal as in it fires in bursts now instead of the constant stream it had been doing, but it still seems like it is spraying too much gas. Im thinking it is either the injectors themselves or the ecm; could it be the prom?
