Injectors in 1990 454	Deral Rogers	9-4-06
My 454 throttle body is pumping way too much fuel into intake. I have rebuilt fuel pressure control(no help),have checked sensors(map,idle air control,temp.)Replaced egr valve,gaskets on throttle body,02 sensor,coil,plugs&wires,ignition contol module,electronic control(brain), Have had engine scoped,no codes at all. Any ideas?

Have you hooked up a scan tool with engine running,looked at all parameters and see if fuel numbers look good.Also check all ground wires.Check fuel pressure and fuel return line to tank for any blockage. Good Luck MIKE
